  • Computer freezes after watching Youtube videos

    - by Roberts
    I had Windows 7 installed all september. But I installed Windows XP Professional back because my computer couldn't handle the new OS. After first boot I tried to install newest flash player (from Adobe website), but it failed. I had my old setup on USB drive and it worked. I don't know is it important or not. I am watching Youtube videos in my free time (almost every hour). After few days the computer started to freeze when I open a page with the video or close the page with video, not while I watch a video. No BSODs. Nothing in Event viewer. I use Firefox only. When computer freezes the sound wont. If iTunes is playing a radio station or is it another video playing in background, the sound wont freeze. Last few days the mouse wont freeze. Its a strange symptom. If I click few times then the cursor will actually freeze. I just want to know where does this problem come from (hardware - graphics card, old motherboard or it's just some glitch in setups). If it's not graphics card then I will be happy. The graphics card is ATI Radeon HD 4650 - brand new. Catalyst 11.8 installed. Things I have tried: Installed newest flash player after a week (the setup didn't fail this time) Installed latest video drivers Deleting cookies Defragmenting hard drive Using TuneUp utilities for computer cleenup Installed latest Mozilla Firefox Cleaned the PC Changed CPU Fan speed almost to max (just to be sure) Things I haven't tried yet: Didn't try playing videos on other browsers What can I do now?

  • Very, very simple asp.net page takes forever to load

    - by John Hoge
    I've got a page that couldn't be more simple: <%@ Page Trace="true" %> <html> <head></head> <body> <h1>Hello World</h1> <a href="/OtherPage.aspx"/>Other Page</a> <p><%=DateTime.Now.ToString()%> </body> </html> ... but it takes forever to load. There is no database or web service call to slow it down. The trace command reveals that the time from Begin PreInot to End Render is .000049 seconds, but the page itself takes several seconds to load. It is a new web site I just created for this test, and just has a web.config & two test files. The only thing in the web.config is access control: <authorization><allow users="domain\me" /><deny users = "*"/></authorization> What else could IIS be doing with all of that time?

  • solution for an offline server

    - by dashmug
    I'm trying to setup a development server at work that will ideally be able to test drive a couple of projects in PHP, Rails, or Django (not always running at the same time). I develop the apps locally on a Mac and then I'll put the projects up on this server for testing with my actual users (non-techies) before deploying to a production server. My problem is that we have a very poor internet connection (almost negligible) at work and doing the usual apt-get/yum/ports (make, clean, install) processes for setting up servers always get their packages from online repositories somewhere. I know I could probably download the source and then compile them myself but that's going to be too much of a hassle for me. I'm thinking about two solutions: Plan A: Run a server VM on my Mac and then use this VM as the source repository for the offline server. I've read about Ubuntu's apt-proxy and it seems to be good enough though I haven't tried it yet. I'm not sure if this is possible but can I simply do apt-get install nginx --downloadonly so that the package and its dependencies will be downloaded into my VM and my server can use the VM as the source repo for apt-get? Plan B: Run a server VM on my Mac (which I can setup/update easily when I'm home) and then clone the VM to the offline development server. Maybe I should simply make the server a VM host so I can simply copy the VM over. I think this is okay for the first-time setup but subsequent updates will take too long (cloning the VM image). If I was working on Windows, I imagine it'd be easier because most services have an installer file that I can download and then run at the server. If you could suggest another way, it would be much appreciated. Update: From Michael Hampton's answer, I found a possible solution which is apt-cacher. I also found this page on Ubuntu's website. I wonder if there is a better tool than this one.

  • Logging Remote Desktop to Servers via Logon Script or GPO or What?

    - by Nate Bross
    The objective here is to start a simple .NET application I've written which captures some environment variables (time, username, computername, etc) upon login. This .NET application subscribes to the Windows "User logout" event. Upon launch, the application captures the above variables, and creates a record in my database, upon logout (which I'm capturing) I update another field in the same record, with the logout time. The above is working exactly as I would like, when I launch the binary, it makes its initial log entry, then waits for the logout event and updates the same record. Restrictions, the .NET binary should be able to live on a share point (\server\share\myapp\v1) so I can update the application to (\server\share\myapp\v2) and simply update the GPO/Logon script. My initial thought was to use the \domaincontroller\sysvol\ directory to store the binary and then update all user accounts to include a call to my application. Can you see any flaws in this approach? My question is this: First, is there anything wrong with my idea above? Second, if so, what is the best way (through group policy or otherwise) to ensure this application launches whenever a session is started on a server?

  • Concurrent users with Quickbooks?

    - by airietis
    I work in a company with 3 people who regularly use the same Quickbooks file. However, they work remotely on different networks. I need to implement a solution that allows all three of us to access Quickbooks at the same time remotely (and each make changes at the same time). We have a spare desktop PC that can be utilized as a server. So, my question is: what is the cheapest and most hassle-free solution to solving this problem? I've considered using application cloud hosting, however, it is very expensive ($40 per user a month) and we are on a tight budget. Is it possible to install Quickbooks on my own server, and have them connect to it remotely? If so, what is the best way to accomplish this? Remote desktop protocol? Or is there a built in feature for this with Quickbooks Premier 2013? EDIT: As MDMarra mentioned, I am looking for a solution that offers true simultaneous access. Will using a dedicated server and having users connect to a VPN be a viable solution?

  • How to disable my laptop's defective keyboard?

    - by Kolink
    I have an Alienware M17x R2, and after a couple years of use I started having problems with the keyboard: Intermittently, and without warning or apparent cause (even if I'm not touching the computer), the S key (and more recently the D key) will start firing incessant signals until I hit the offending key. I've been using a USB keyboard, which is conveniently exactly the right size to fit over the built-in keyboard without touching any buttons. However, even as I type the defective keyboard will fire its stream of signals. I have contacted Dell about this, twice in fact. The first time, I was just bluntly told that they don't ship replacement keyboards. The second time I was told that they did, but they were out of stock and they would contact me when they were in stock again. They haven't contacted me since. I can't seem to work out which device to disable in the device manager. Here's a screenshot of what I have: None of the keyboard devices have "Disable" in their context menus, only "Uninstall"... so you'll understand if I'm hesitant to try anything myself. Any advice on how to fix this?

  • How to Monitor Network in Medium-Sized Company?

    - by Kyle Lowry
    I work at a medium sized company (100+ employees). An issue that has been cropping up is network performance, internet access in particular. We have about 70 or more computers, a mix of Mac OS X and Windows XP & 7 machines. We have several servers (Exchange server, PC file servers, MS SQL, Blackberry, FTP, Mac server, etc). There are four main switches, a SonicWall firewall, and probably a couple routers in the server room with a dozen or so more scattered around the building. The network structure has grown organically over a number of years; and, as far as I know, there really isn't a monitoring solution in place. When we experience network issues (slow connections, dropped packets, and so on), our general solution is to power cycle some hardware or go around to each employee and ask them if they are uploading/downloading any large files. This is really inefficient and time consuming, and it does not allow us to monitor the network, tackling potential problems proactively. I would like to find a solution that would allow me to monitor network usage company-wide in real time, with detail going down to the individual computer, ideally. Given the hodgepodge of equipment and operating systems, what would be the best way to set up some kind of monitoring solution? Hardware, software, restructuring our network architecture?

  • XBMC remote control key repeat

    - by Amigable Clark Kant
    Those who have used XBMC with a WiFi remote, such as an Android or iOS device with the official XBMC remotes, have probably seen this at one time or another: your remote stops working, when you press a key, that key is repeated very fast. Sometimes you can break the key repeat loop by pressing that same key again. Sometimes (as this particular morning) you can not. This problem has existed for literally years (it even occurs on the old XBOX only builds) but there seems to be no definite explanation as to what is causing it. I am asking for a workaround. (If you Google, you can find threads were people are ridiculed for bringing up this problem, which is one reason I ask here instead of on the official forums. Also the fact that this problem has persisted for so many years.) I am running, right now, XBMCBuntu Live Eden and the latest official iOS remote. Although, I have seen this problem on all combinations of remotes and XBMC versions I have tried over the years, which are many. (XBMC on Windows, Linux, OSX, remotes on Android and iOS.) Link to bug #136 for the Android remote. It's marked as "fixed" as of client version 636, but the problem is seen again in rev 730. Go figure. There is something fundamentally wrong with how keypresses are sent from the various remotes to XBMC, since this problem is seen across time, XBMC versions and iOS/Android.

  • VMWare Server modifying files related to paused VMs, is this expected?

    - by David Spillett
    While refreshing the backup of a VM used for testing, I experienced the following warning from tar: tar: /VMsR0/cli_noddyco_test/VM2K8_32_web.vmem: file changed as we read it The VMs in question were paused at the time. My first though was that I'd mixed up the machines and was trying to backup something that was still actively running. To be sure I unpaused and properly shut down the VM, and the vmem files that tar reported changing vanished as I would expect. Is it normal for VMWare Server to touch or alter files for paused VMs like this, or is there likely something amiss with our setup? If this is expected behaviour, is just touching the vmem file (and so altering the last modification date without actually changing content)? If it is normal for files relating to paused VMs to be updated I shall have to revise our backup procedures to make sure the VMs are fully shut down fully rather than just pausing them (this isn't a problem, but it seems strange and I'd prefer to understand what VMWare is doing and why instead of just dismissing it as "one of those things" and working around it). For further detail: the host in question is VMWare Server version 2.0.2 running on 64-bit Debian/Lenny, and that VM did not have a snapshots at the time. We have backed up paused VMs this way in the past with no such warnings from tar.

  • How can I create a macro that acts on a relative reference rather than an absolute reference to cell A1?

    - by Bruce
    I have a master rent statement in an Excel 2007 (macro enabled) spreadsheet that shows all tenants in rows with columns formed by the months. Each tenant then has a separate rent statement sheet like the one below that pulls the data through from the master rent statement and all I do then is to copy the last 4 columns to the right and add them to the right, just renaming the month labelled as ‘rent due’ with the current month and then hiding the previous last 4 columns to the left so that the statement always shows the previous month's activity and the amount due for the current month: I used a macro to speed up the creation of these statements, but then found that in some cases the result was wrong and needed major correction because the macro use absolute references i.e. its starting position was relative to cell A1 whereas some of my rent worksheets commence from a different column and in some cases from a different column and a different row. I have tried recording the macro with 'Use relative references' but when trying to use the macro it only gets part way through its operation before it stops and the message appears: Run time error '1004' Application defined or object defined error with the option to End or Debug or go to Help and then I'm stuck as I don't know how to debug and work in VBA or understand what has gone wrong. I want to record a single macro that always remains relative to the last 'Total Due' column heading (in the sample, it’s cell FF3 but on another worksheet could be cell GA26) and thus enables me regardless of where on the worksheet the rent statement is placed to add through my recorded macro a further four columns with updated dates and a repositioned 'Total Due' summary (in the sample in cells FE23 and FF23). The contents of cells FE23 and FE22 are always the same number of rows from the 'Sample Rent Statement, Service Charge and Sub Total' rows. I've searched on the web and in the help files of Excel 2007 but have been totally stumped by this, so currently I have to re-record a quantity of macros each month to cover all of the permutations of the worksheets in my Excel rent workbook, which is starting to become pointless in terms of saving time. Does someone know a solution to this problem please?!

  • Screen randomly goes blue/black/white

    - by FubsyGamer
    Problem Randomly, while using my computer, the monitor goes dark grey/almost black, or it goes white with faint grey vertical lines, or it goes blue with black vertical lines. It's as if the computer powers off. People tell me I sign out of Skype, Spotify stops playing when it happens, etc. When I look at the tower, it doesn't seem like it's off at all. Nothing changes, fans are spinning, lights are on, etc. If you were only looking at the tower, you'd never know there was a problem The only way I can get it to come back up is to push and hold the power button and turn it off, then back on This never happens while I'm playing video games. I've done 5-6 hour sessions of League of Legends, and it doesn't do anything When I'm just browsing the web, reading email, checking Reddit, etc, it happens all the time. It can happen multiple times in a session, it usually takes only about 5 minutes from the time I start browsing to when the computer crashes This started happening after I moved to a new apartment (this has to be relevant somehow, it was not happening where I lived before) There is nothing in the crash logs or event logs System Specs i5 2500k CPU AMD Radeon 6800 GPU Gigabyte z68a-d3h-b3 motherboard WD VelociRaptor 1 TB HDD Screenshots Device manager About screen Things I have tried I was getting a WMI Error in my event logs, but I fixed it using Microsoft's fix, KB 2545227 I was using Windows 8. I wiped the HDD and downgraded to Windows 7 64 bit I took out the video card and used a can of air to totally clean out the video card, all fans, and the inside of the computer in general. I made sure all of the video card pins were fine, then reconnected it I tried to update my motherboard BIOS, but anything I downloaded from Gigabyte was only for 32 bit machines, not 64. I don't even know how to tell what my motherboard BIOS is at right now I am using a power strip, and anything else connected to it works just fine If I re-seat the monitor cable while this is happening, nothing changes Please, help me. I've been battling this for several weeks now, and it's so frustrating it makes me not even want to use the computer.

  • Scanning to network share

    - by tking
    In our environment we have several printers with the scan to folder functionality set up. It worked pretty well. Long story short- I needed to reboot our file server one evening (the server whose $hares where all the scans go), upon on boot up I received a message stating the name of the file server (i.e AcmeFS1; Windows Server 2003) could not be used because there was a duplicate name on the network. I found that somehow another printer on the network was using the name of the file server. Weird - I know. People could no longer scan to their folders. I ran an nbtstat on the file server and found that the local netbios name table was empty. I renamed the offending printer and rebooted the file server once more. This time, no error, and once I ran nbtstat again, I found that correct name and domain in the local netbios name table. Problem is, scan to folder is still not working. I know this was working before I rebooted the file server the first time. Anyone have any idea what is going on and how to fix? Thanks. FIXED: Not sure why the reboot didnt fix it but I restarted the "Server" service on the file server and the problem went away.

  • GIT and Django Projects

    - by Garfonzo
    I have two servers, a Dev server and a Production server. The Production server runs a live Django site, while the Dev server has a copy of the Django project. I use the Dev server to work on the Django site, make improvements, fix bugs, etc. Once I am satisfied with how the Dev version is working, I move the whole Django directory from the Dev server and replace the same directory on the Production server. The two servers are not on the same LAN so the process is not straight forward. There are a few issues with this that I am having so far. Moving the whole directory is laborious and time consuming If I only change a few files, it is even move tedious to replace a few files than the whole directory since the project is getting fairly large and I worry that I'll miss something I often run into permission issues after I've moved things It's super inefficient, and, due to lack of time, I haven't bothered figuring out a new method. Now it's just getting out of hand and i need to address the situation. I am thinking I need to move to a GIT repository for this process. But my question is how would I set this all up? Do I host the repository on the Production server, pull from the Dev server, do work, then commit? Then I would pull from the Production server (same server the repo is hosted on) to run the current working version? Do I host the repo on the Dev Server, pulling from the same server to do work on the repo, then pull a working version onto the Production server? Should I be hosting the repo on a different server than the Production server and the Dev server (a third server)? Are there any special considerations with Django and repos that I need to worry about? Thanks for the help :)

  • PHP Not Automatically Updating With ?reload=1

    - by user32007
    A friend built a ranking system on his site and I am trying to host in on mine via wordpress and godaddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error. His page is at: jeremynoeljohnson .com/yakezieclub My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error. Any idea why this might be happening? Any settings that I might need to change? Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him. Here's the reload part: $cachefile = "rankings.html"; $daycachefile = "rankings_history.xml"; $cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes $daycachetime = (60 * 60) * 24; // every 24 hours, the history will be written to - or whenever the page is requested after 24 hours has passed $writenewdata = false; if (!empty($_GET['reload'])) { if ($_GET['reload']== 1) { $cachetime = 1; } } if (!empty($_GET['reloadhistory'])) { if ($_GET['reloadhistory'] == 1) { $daycachetime = 1; $cachetime = 1; } } if (file_exists($daycachefile) && (time() - $daycachetime < filemtime($daycachefile))) { // Do nothing } else { $writenewdata = true; $cachetime = 1; } // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile))) { include($cachefile); echo ""; exit; } ob_start(); // start the output buffer ?

  • Problems reviving old pc including graphics card issue.

    - by Mick
    I have a PC that seemed to have died years ago that I am trying to revive. It has a dual core athlon processor and a gigabyte motherboard. It had two dual output graphics cards, and I have long since forgotten which output would print out the diagnostic information as the PC starts up. Also I suspect that the resolution set on all the monitors was probably higher than my current single monitor is capable of displaying. The motherboard also has a built in graphics card, so I thought it may be simplest to remove both the graphics cards and plug my monitor into the onboard graphics just while I get things going. Does that seem sensible? Now the other problem: The PC has two hard drives. I have no idea which one is the primary one it is attempting to boot from. When I power up, the fan comes on and I hear some chuga-chuga-pause chuga-chuga-pause repeat indefinitely. I'm not sure which device is making the noise. There are no-beeps at any time. I see nothing on the screen at any time, not even for a second. Any suggestions? EDIT: If T start up the PC without the power connected to the CDrom there is no chuga-chugan noise.

  • Amazon EC2 - Free memory

    - by Damo
    We have an amazon ec2 small instance running and over the past few days we noticed that the memory is going down and down. On the small instance, we are running apache and tomcat6 Tomcat is started with the following JVM parameters -Xms32m -Xmx128m -XX:PermSize=128m -XX:MaxPermSize=256m We use nagios to monitor stuff like updates to apply, free disk space and memory. Everything else is behaving as expected but our memory is going down all the time. Our app receives approx half a million hits a day When I shutdown apache and tomcat, and ran free -m, we had only 594mb of memory free out out of the 1.7gb of memory. Not much else is running on the small instance and when running the top command I cannot see where the memory is going. The app we run on tomcat is a grails webapp. Could there be a possibility that there is a memory leak within our application? I read online and folks say that a small amazon instance is perfect for running apach and tomcat. I found a few posts online that showed how to setup apache and tomcat to limit the memory usage and I have already performed those steps. The memory is not being used up as quick but the memory is still decreasing over time. We have other amazone ec2 small instances running grails apps and the memory is fairly standard on those nodes. But they would not be receiving as much traffic Just to add, when I run the top command on the problem server, I cannot see where all the memory is being used Any help with this is greatly appreciated The output of free -m when run on my server is as follows total used free shared buffers cached Mem: 1657 1380 277 0 158 773 -/+ buffers/cache: 447 1209 Swap: 895 0 895 In your opinion, does this look ok? At what stage would the OS give back memory, would it wait to the memory reaches 0% or is this OS dependent?

  • Ubuntu server 10.04 disconnects after short periods of inactivity on my site

    - by user57019
    I'm new to Ubuntu (installed it for the first time just a couple of days ago on my server). I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing. Whenever I go to sleep and there's no activity on my server (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online! I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active. I was previously using XAMPP on my laptop with Windows XP and that worked 24/7 so I don't think it's anything with my router or ISP. This is driving me crazy! My site is down all the time I'm in school as I have no possibility to restart the server if it becomes offline. Does anyone have a clue to what could be wrong?

  • Vim move cursor one character in insert mode without arrow keys

    - by bolov
    This might seem a little too overboard, but I switched to vim and I so happy about the workflow now. I try to discipline myself not to use the arrow keys, as keeping the hands on the alfa-keys all the time is such a big thing when writing. So when I need to navigate I get out of insert mode, move in normal mode and get back in insert mode. There is an exception where this is actually more disrupting: I use clang complete with snippets and super tab which is great. Except every time I get a function auto completed after I fill in the parameters I am left with the cursor before ) so to continue I have to move the cursor one character to the right. As you can imagine this happens very often. The only options I have (as far as I know) are : Escla or ?, and I am not happy about neither of them. The first one makes me hit 3 keys for just a simple 1 character cursor move, the second one makes me move my hand to the arrow keys. A third option would be to map CTRL-L or smth to ?. So what is the best way of doing this? //snippets (clang complete + supertab): foo($`param1`, $`param2`) //after completion: foo(var1, var2|) ^ ^ | | I am here | Need to be here | denotes cursor position

  • Audit file removal (auditctl)

    - by user1513039
    For some reason, some script or program is removing a pid file for the service on the linux server (centos5.4 / 2.6.18-308.4.1.el5xen). I suspect a faulty cron script, but manual investigation did not lead me to it. And i still want to track it down. Have been using auditctl rule: auditctl -w /var/run/some_service.pid -p w Which helped me to see something, but not quite exactly what i wanted: type=PATH msg=audit(11/12/2013 09:07:43.199:432577) : item=1 name=/var/run/some_service.pid inode=12419227 dev=fd:00 mode=file,644 ouid=root ogid=root rdev=00:00 type=SYSCALL msg=audit(11/12/2013 09:07:43.199:432577) : arch=x86_64 syscall=unlink success=yes exit=0 a0=7fff7dd46dd0 a1=1 a2=2 a3=127feb90 items=2 ppid=3454 pid=6227 auid=root uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=pts0 ses=38138 comm=rm exe=/bin/rm key=(null) Problem here is that i see ppid of the script that removed the file, but at the analysis time the (p)pids are already invalid as probably scripts/programs have been shutdown. Imagine a cron script deleting the file. So i need some way to expand/add audit rule(s) to be able to trace the parents of the /bin/rm at the time of removal. I have been thinking to add some rule to monitor all process creation, something like: auditctl -a task,always But this happen to be very resource intensive. So i need help or advice how to combine these rules, or how to expand any of the rules to help track the script/program. Thanks.

  • thought about shared storage (NFS, Lustre) [closed]

    - by user134880
    Possible Duplicate: Can you help me with my capacity planning? Now I habe small cluster with total of 8 nodes. 6 of them are computing nodes (apache and vmware) and 2 nodes are for storage. 2 storage nodes are identical. Each storage server is linux box with 8 x 1Tb WD RE4 in soft raid 10. 1st box is master and 2nd is slave. Data is mirrored with DRDB. We export NFSv4 shares to Apache (for document root) and iSCSI to Vmware. Now all is working pretty good and stable. But it will be soon time to upgrade our system. I have been thinking of Lustre. Does some one has any real experience with Lustre or NFS medium clusters? Will it be good idea just to upgrade server and change hdd's to 3Tb ? With NFS we will always have only 2 servers to maintain (one primary and one slave). Thanks. QUESTIONS: 1) Does some one used Lustre? In production? I have seen a lot of info about how it is hard to setup Lustre because you need to compile own kernel and patches. It's answers from newbies. Is there some one who has used Lustre for some period of time? 2) About disk upgrades - it's only description of strategy. I'm not asking if it is enough 3Tb or not. I just ask if it is right just to replace hdds instead of adding new server (like with Lustre) Thanks again.

  • Good Hosting Providers With Zend Framework Support [closed]

    - by manyxcxi
    I currently use ixwebhosting for my hosting services. They're cheap and work (most of the time). The databases are horribly slow, the servers are horribly slow, and their support (though usually prompt) is tough to deal with. That being said, they're cheap, I've got like 20 domains hosted in my account, none of them are high volume, and they work JUST good enough- until today. This isn't meant to be a condemnation of ixwh though. Their prices are very low for what they do offer and most things work just fine, most of the time. I need to be able to host web apps written with Zend Framework in a fairly easy fashion. The server performance can't be worse than what I've already had (a pretty low hurdle to clear), and I don't want to spend $30/mo. These are not money making websites- they're projects. My requirements are PHP 5.3, ZF support, MySQL databases, multiple domains- not much. Who should I look at, and who should I look out for?

  • Giving the root user priority to maintain Debian (while server collapsing under heavy load)

    - by Saix
    Is there any way to setup Debian to prioritize any or specific root's activity before every other? For instance, several times per year something gets wrong (usually man's fault by overstressing apache/mysql) and system gets unresponsive under heavy load like 200 (8-core cpu). I know there are limits for php scripts to run then kill, but that's not the way because this limit has to be at least 45 minutes long. The problem is, until I'm able to login via SSH and let apache/mysql restart under this server stress, it nearly hits these 45 minutes anyway. Also hardware restart causing usually to run fsck at boot time on all harddrives since it's usually pretty long the box haven't been restarted. I was told it's really not good idea disabling fsck but then again, it takes more then hour to complete. What is the fastest way to restart apache/mysql? Is there any way to give ssh users or root user higher priority so the logging in and completing these restarts (rather stops though) commands wouldn't take so long? One comes to my mind.. use NICE for apache/mysql but no way. I can't risk limiting those two vital apps 24/7 or could I? I'm a little bit scared if any other system process wouldn't slow the pages down too much. Any backup process, swap (if any) etc. There is pretty heavy PHP framework with 20k visits a day, so it needs every hw/sw resource available. I can't throttle it the whole time, just in certain points when system gets unresponsive, so I could maintain it.

  • Can installing Linux or Grub make all of my operating systems slow?

    - by Geore Shg
    I installed Linux Mint 64-bit recently but it freezes up all the time. Not only that, but Grub wouldn't detect Windows. I thought it was just an issue with Linux Mint so I booted into Ubuntu - however that froze up as well. I downloaded Fedora to replace Linux Mint with, but that also freezes up. I finally gave up trying to repair Grub, burning a supergrub grub2 disk and using that to boot into Windows. Windows now freezes up as well. I installed a new copy of Windows on a different drive but to no avail. Right before all this started my computer was running very smoothly. I am wondering if the installation of Linux Mint, the reinstallation of Grub, or me messing with the BIOS (when I was attempting to repair Grub) could have done something drastic enough that everything is slow now? I realize that computers get gradually slower over time, but this was in no way gradual and it happened directly after the installation of Linux Mint. If so, what should I do?

  • One single page showing 3 requests (also printing the headers)

    - by Korcholis
    Someone in my studio designed a webpage some years ago, and now the client decided to change the server (he moved to a Linux Apache server running Gen2 SMP, 64 bits, PHP version 5.3.8, Standard MYSQL version 5). It suddenly started to do weird things. When clicking on a link that requires login, the page redirects you to the login page using header() function in PHP. Curiously, the page shows this: OK The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. HTTP/1.1 200 OK Date: Mon, 15 Oct 2012 17:27:32 GMT Server: Apache/2.2.22 (Unix) FrontPage/5.0.2.2635 X-Powered-By: PHP/5.3.8 Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Keep-Alive: timeout=5, max=399 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/html 232c Then the page itself, and then, another header: 0 1f4 OK The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. 0 What's most intriguing is that if you refresh the page or hit enter on the url, it loads correctly. I've been checking the logs, and it only blames of an inexisting favicon. I also checked the .htaccess, everything was correct (RewriteBase was / as intended, and the only stuff there is another rule that moves ^en/ requests to request?lang=en. Has anyone faced something like this? Edit: IE doesn't trigger these two headers. This is getting wierder.

  • Reading log files from web application

    - by Egorinsk
    Hi! I want to write a small PHP application for monitoring logs on a Debian server, including syslog logs and Apache/PHP messages. The problem here is that Apache user (www-data) has no access to /var/log directory. What would be the best way to grant an access to logs for PHP application? Let's assume that log files can be really large, like hundreds of megabytes. I have some ideas: Write a shell script that would be run via sudo and tail last 512 Kb of log into a separate file that can be read by application - that's ineffective, because of forking a new process and having to read data twice Add www-data to adm group (that can read logs) - that's insecure Start a PHP process via cron every minute to read logs — that's not very good, because it doesn't allow real-time monitoring. Also, this script will be started even when I don't read logs, and consume CPU time (server is in the cloud, and I'll have to pay for it) Create a hardlink for all log files with lowered permissions - I guess, that won't work because logrotate could recreate log files and they'll change inode number. Start a separate nginx/Apache server under privileged user that may read logs. Maybe anyone got a better solution?
