• Resuming downloads in Firefox

  - by Kim

  Unfortunately, Firefox still has failed to add the option to resume downloads. I've ran into this problem SO MANY times, and in my previous searches I found posts saying Firefox was going to fix that. As of 3.6.3 they haven't. I just tried Free Download Manager (FDM), again, having the Firefox addon Flashgot use it. The download gets passed to FDM, and fails, giving the error message "access denied, invalid username or password." No password was required. The site I'm trying to get the file from is turbobit.net, which limits downloads speeds to 100kb/sec, and has a 59 second countdown before you get the link. I guess it's transparently using a password on their end. If I just download normally (save to disk) the download starts fine, but it fails after 30 minutes to 1 hour (always different), and my Wi-fi connection will stop briefly - and I have to start all over. So I will never be able to download a large file. I also tried DTA instead of FMD with Flashgot, and I get an "access denied" message in DTA. Again, I reloaded - waited the 59 seconds, and download w/Firefox, and the download starts fine. The failure message in the Firefox Downloads window is "source file at http... could not be read." Any help would be greatly appreciated. When is Firefox going to finally add the ability to resume downloads????? Is there some other software I haven't found using Google that will work?

• COMPAQ Tower No Signal to monitor

  - by Lancelot

  I received a Compaq tower: Compaq Presario SR1224NX Onboard VGA Windows XP SP2 from a friend. My plan was to turn this into an Ubuntu Server. It booted up with no problems even with the Ubuntu live disc. After a normal shutdown (not unplugging the power cord and not doing a hard shutdown with the power button), it would not restart even after SEVERAL attempts. I realized the light next to the power supply would flash very rapidly. I researched and found out it was one of two things: a dead power supply or the cables to the motherboard and to the disks might be faulty, etc. Thus, I checked to ensure the cables were fine(and they were). I purchased a Power Supply (this one has 400 watts, the initial had 250) and installed it. The tower was able to boot into the live disk and everything. After a normal shutdown, it now restarts but is not sending signal to my monitor. I have tried several monitors in which I know work perfectly but not with this tower (I recall that it did show display after replacing the power supply). The monitors are ACER. This is different than most "no Signal" problems since I am not using an external Video Card, this is onboard VGA.

• MicroSD card getting corrupted for no good reason

  - by ChaosR

  I recently bought an MicroSD card online. It's a Sandisk 16GB class 2. However, it has a nasty problem. Every time I fill it with my data, the fat tables get corrupted. I've tried reformatting it, blanking it, doesn't seem to solve the problem. I have tried windows and linux (ubuntu), both have the problem. I've used my usb microsd readers, and even tried putting it in my phone and putting data on it from there. All have this problem. Now the really odd thing is, besides the corrupted file tables, no programs can find anything wrong with the hardware. I've tried both chkdisk and "badblocks -w", neither give any type of error. Now I don't know if the actual data gets corrupted, or if its just filesystem tables. What happens is that one or more folders start showing a load of chinese-charred (random UTF8 symbols I suppose) folders and files, and it is impossible to do anything with those. All the other data (outside of the corrupted folders) seems fine. I've tried to test it, and the problem doesn't seem to show up until I fill the disk upto about 3~4GB. After that I can still access the data. But as soon as I eject/safely remove/unmount it, the bad things happen somehow. Next time I plug it in, the folders I most recently wrote to (but sometimes also the folders I wrote the time before last time to) are all gibberish. Does anybody have any clue what might be going on here? EDIT: It seems I can't even put ext3 or ext4 on it, they both complain about a corrupted journal. Gheh, guess something is really broken here.

• mac gets stuck in a blue screen during boot

  - by user10826

  Hi, a macbook pro 2008 unibody, after restart gets stuck in a blue screen. I used the Leopard disk and I verified and repaired permissions, which seem to be a problem, because the assistant found some wrong files. After restart I got the same problem. After googling I reset PRAM and the other (I do not remember the name now). Same problem. I check that I can boot in safe mode, although it is a lot slower. So before anything I try to make a time machine backup, hoping that I can be done from safe mode. First question: If it works, is it possible to do a clean leopard install (I do not like Snow) and migrate all user accounts from the backup, although it was done in safe mode? Second question: I read about the feature "archive and install" from the leopard disc. Is it reliable? Because I am afraid of losing all data ... Third question: I think this boot stuck has to do with the load of some program or service. It would explain why the computer does boot on safe mode and not in the normal one. I would then like to check what the computer loads during boot, but in more detail that with the information provided from /system preferecens/account/start, because there I removed everything. Where can I find more advanced information? And, if I remove programs from the safe mode, will it be effective druing the normal boot? Thanks

• CentOS vps is randomly rebooting

• Command line scripts to restore the 4 system databases of MS SQL Server 2008

  - by ciscokid

  Hi there, can someone give me some advice on how to restore the 4 system databases (master, msdb, model, tempdb) of a sql server 2008 please? I've already done some testing myself (on restoring the master database) with the following commad line script as a result: ::set variables set dbname=master set dbdirectory=C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA title Restoring %dbname% database net stop mssqlserver cd C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Binn sqlservr -m sqlcmd -Slocalhost -E -Q "restore database master from disk='c:\master.bak' WITH REPLACE" net start mssqlserver pause After the execution of the 'sqlservr -m' command (used to start the server instance in single-user mode, which is only necessary when restoring the MASTER database), the script stops. So in order to execute the last 2 commands I need to separate the script into 2 smaller scripts, and run them one after the other. Does anyone has an idea on how I can merge them into one single script that runs completely without any interruption? I also want to restore the other 3 system databases using command line scripts like this one. Can someone please advice me how I need to go on? I've already noticed that restoring the temdb is not so easy, but there has to be a way... Looking forward to your advice!

• Virtual Windows 2008 Server Activation with ESX

  - by Logman

  I had a decommissioned server (Dell PE2950) that we could still use, it had OEM Windows 2003 Std on it but wanted to use it as a new host with VMware ESX5 to put a couple legacy severs on it. I wiped it clean and maxed out the memory. But when I added the memory I noticed the product key sticker was a "WindowsServer08 Std 1-4cpu" product key, and it also had a Virtual Key. Not sure why it had Win2003 and not Win2008 from the start, but I would like to use that license if I can. The virtual host would stay on the same physical server, so there shouldn't be a problem with licensing... but I do not want to use Hyper-V unless I can not help it. I have installed ESX5 on the server, but I cannot get the Windows 2008 server to activate. The product key is hard to read, and I have checked the key quite a few times. But my question is... Is it because Hyper-V was not installed on the host? But I thought you could use the product key alone on a virtual host? Maybe because I am not using a Dell Windows 2008 disk but iso from MS directly via the Volumne Licensing site? EDIT: well, Im pretty sure I got the product key correct. If its not the product key, could the activation problem be because Im not using hyper-v or maybe the correct install dvd? EDIT2: maybe because I added 28GB of memory? Originally 4GB...

• Is there a way to exclude a specific drive vdi from "snapshots" in VirtualBox?

  - by Graza

  ...or is there another space-efficient way of dealing with the page/swap file of the Guest O/S? I've realised that its quite possible/likely that one of the things which "bloats" the snapshot/diff vdi's when a snapshot is taken is the guest operating system's pagefile. For example, say I have a 2Gb swap-file in a Windows guest OS, and over the course of a few weeks the usage of the swap file has gone over 1Gb a couple of times. When I next create a snapshot, it seems likely that I'd be almost guaranteed around 1Gb of space taken up in the new differencing disk just because of changes in the swap file. Obviously (provided I never did "live" snapshots on running or paused machines, and only ever did them when the machine was shut down), I would not need any of the information in the swap file to be saved. So this would simply be a waste of 1Gb. I'm wondering if there's a way to attach a vdi to a VM and flag it as "exclude from snapshots" - which would mean I could put the swap file on a different vdi which would never be included in a snapshot. Or if anyone has any other suggestions. Or an explanation about why it might not be an issue. I could obviously delete and recreate a swap drive vdi every time I did a snapshot to achieve the same effect, but this is a little more effort than simply clicking "create snapshot"....

• Notebook Operating System with extreme support cycles/security updates

  - by leto

  Hello there, after reading the announcements about Mac OS X "Lion" and Apples political decision, I've had enough. I'm a longtime Apple User since 1992, have always felt at home there, but am trying to switch to alternative Operating System since a year. I've also been working with Unix machines since 2001, so I'm looking in one of the free Unices or a Linux. Since I last looked at the desktop in 2002 choke much has changed, it seems. So I'm lost once more in the war between desktop environments and software. To be honest: I don't care what it's name is, I want to get my job done. Here's what I set me as landmark for an operating system/software to be considered: Has to be atleast four years old Has to supply security updates for current release for atleast a year Production quality stability for the whole desktop environment (!) No f****g commercial stuff that tends to supply me with privacy invading App Store or Cloud space So far I'm running a MacBook from 2007, 4 Gig memory, 250 Gig disk and I need: IMAPs for Mail since 1995 Webbrowser sic Shell Keeping current with Updates/Upgrades with no more than 5 Minutes spent in entering commands (makes it hard for OpenBSD ;-) ) A desktop filemanger would be nice, but is a bonus. What can you suggest as operating system? The one with the longest support cycles and best chance to survive the next 10 years will win a new user, even sending patches when needed :-) Greets

• CLI package to replace Plesk

  - by dotancohen

  Myself and another programmer are tasked with maintaining a few webservers. I prefer CLI tools, she prefers Plesk. However, I am adamant about not installing Plesk for quite a few reasons. I have written a small Python script for adding new domains, and now I am about to add the ability to configure email addresses while abstracting the details of Postfix from her. Before I go that route, I have googled to see if anything already exists, and am surprised that I have come up with nothing! Are there any mature, stable "control panels" or "server admin" tools like Plesk, but which are accessed via the CLI over SSH? I am looking for the following features: Add / remove / configure domains served by Apache. Add / remove / configure email boxes and mail groups. Add / remove MySQL databases, users, and configure users to databases. Provide basic monitoring of "server health", that is: memory usage, disk usage, CPU usage, bandwidth usage. Possibly set up STFP accounts so that only specific FTP users could access specific /var/www/someSite/ directories. Note that I was unsure if this question is OT for ServerFault. As per the ServerFault about page (There seems to be no more FAQ) this question meets two of the "ask about" criterion and zero of the "don't ask about" with the possible exception of being opinion-based. Therefore, to keep on-topic, I would like to know about the available applications but we should be subjective and less opinionated. Thank you!

• running chkdsk /F on a large mounted NTFS image file gets BSOD (Windows Vista)

  - by Citizentools

  Using ddrescue, I've created ISO files from the C: and D: drives on my Windows XP laptop's harddisk (after the laptop stopped booting and chkdsk etc. wouldn't fix it). I was able to mount the 60 GB D.iso file use OSFmount, and successfully recreated the D: drive on another laptop. The C.iso image is more problematic. ddrescue left about 3mb unrecovered of 85 GB total, after multiple passes (no big worries about this) and I'm able to mount it with OSFmount on a Windows Vista laptop. However, when I run chkdsk /F /V on the mounted drive (which was mounted as H:), I consistently get a blue screen (BSOD). CHKDSK makes it through the first three passes, including index fixing and security descriptor fixes, without errors, but triggers a BSOD when it attempts to fix the volume records or bitmap If I attempt to fix the drive by clicking on Properties-Tools-Error checking-Check Now-Automatically fix file system errors, I get an alert box reading "WIndows was unable to complete the disk check." I'd try a tool other than OSFMount, but it's the only thing I've found so far that will mount large ISO files, and it has worked for me up to now in this process. [Update 2011-11-13 18:41 EST] Just ran the same process using the original Windows XP laptop, with a different internal drive, and chkdsk worked like a champ. So the question is still interesting, but decidedly less urgent.

• Possible boot conflict?

  - by Evan Kroske

  I was installing Ubuntu on a computer on which Windows XP was already installed. The computer has multiple hard drive bays, so I decided to remove the XP HDD and install Ubuntu on a blank HDD when it was the only HDD in the system. Unfortunately, if I now try to boot Ubuntu with the Windows XP drive in the second slot, nothing will boot. However, if Windows XP is in the first slot, it will boot fine. Can anybody explain why this happens? When I was checking out the BIOS to see if something was messed up, I discovered that when Ubuntu is in the first slot, the BIOS doesn't recognize any HDDs. However, if XP is in the first slot, the BIOS recognizes both drives. Any hypotheses about why this happens? Edit: Here's the setup. I have an old server with seven SCSI HDD slots. I have five identical 68 Gb SCSI drives, but I can keep only two plugged in. XP is still installed on the first drive, but I reinstalled Ubuntu on the second drive and had Grub overwrite the XP bootloader on the first drive. Now, the setup works fine, and I can use Grub to load either XP or Ubuntu. However, if I plug in another identical blank HDD in the third slot, the computer recognizes only the XP drive and doesn't boot. Grub starts to load, then gives me a "disk not found" error. Running ls from the grub rescue prompt only shows one drive with two partitions. I guess this is a BIOS problem, but I'd still like to know what triggers it. What about a blank drive could cause the BIOS to freak out?

• Free software for backing up an attached network drive

  - by Richard

  My wireless router comes with a USB connector which allows me to plug an external hard drive in and it'll act as a Network Attached Storage. The problem is that I want to backup this hard-drive to the external drive of another computer so that if the NAS drive fails, I don't lose everything. However, Windows 7 Backup refuses to include the NAS as a location to backup. I can't fool it by mapping it to a drive letter either. Google presents lots of pages on how to backup files to a NAS, but not the other way around. Can anyone advise me on free software which can do incremental backups of a NAS drive to an external drive attached the computer it is running on? I'm aware of this question but the top answers have one or more of the following issues: They aren't free. The free version cannot backup a NAS. They cannot do incremental backups. They're just a script and therefore have limited other functionality (eg. disk space management, scheduling, compression, etc.etc.)

• Can I use a Drobo FS over the internet? -Or alternative?

  - by SeniorShizzle

  I have a lot of files. A HUGE Aperture library, lots of design work from Photoshop, and a rather large iTunes library too. I really want to get a Drobo FS, the networked one, to store all of my stuff on, so that I can get to it from my MacBook Air (which obviously with its minuscule 64GB drive can't hold my Aperture library by itself) and my iMac which is my main powerhouse. The dealbreaker for me is that I NEED to be able to access my Aperture library, and especially my iTunes library from across the internet. I understand that it will probably be slow and everything, but there's nothing else I can do besides hauling around a huge hard drive with me. So, is there any way I can somehow share my Drobo across the internet, on a VPN or something? My other alternative is to upload everything to my web host, FatCow, which offers unlimited disk space (something I hope to make them regret) and then access it using Expandrive. My only thoughts with this are that with the Drobo, any work that I do locally will be much snappier than if I have to work everything off the cloud. Any suggestions about alternatives would also be welcome.

• Asus K55VM usb 3.0 issue

  - by user2141481

  Good day superusers! I own the above laptop and I found out that there are some unknown and unusual issues with usb 3.0 ports. I haven't noticed anything strange until now. I got a new toshiba usb 3.0 external hdd and when I try to copy larger amount of data from my disk to the external hdd, the OS(windows 7) randomly starts ignoring the external hdd. It doesn't shut it down, it kinda just stops responding but the light on the hdd is still lit. I get an error that the files cannot be copied. I have reinstalled windows 7, installed all drivers(including intel chipset drivers of course) and the issue is still present. It acts normal when copying small amount of data. Also, I heard that some intel chipsets have an issue with usb, something about the connectors not transferring power when the usb device enters some kind of "low power mode" causing the device to stop responding and you need to plug it out and in again. But the thing is, my Intel® Chief River Chipset HM76 is not on the list of affected hardware(not ENTIRELY sure though). If anyone has any idea of what the problem to this might be, I'd be greatful. Edit: The hdd works perfectly fine even for large amounts of data if plugged in the usb 2.0 port!

• How to set up RAID-0 first time on new PC?

  - by jasondavis

  I have built basic PC's in the past but have never used a RAID array at all. SO now I am buying parts to build my new PC, it will be an intel i7 processor. My motherboard will have RAID support which I will use instead of an aftermarket raid controller for now. Also I plan to use 2 SSD drives in RAID-0 for my windows 7 OS. (Please note that I am aware of the issues with doing this, including lack of TRIM support when using RAID with SSD drives. I am OK with it not working as I can just re[place the drives in a year or so or wheneer they become more sluggish). SO here is my question part. If I assemble the motherboard, PSU, processor, RAM, vidm card, etc and then go to turn the PC on, it will have the 2 SSD drives hooked up. so I assume I will then soon the BIOS screen before I install windows? How to I go about making the 2 drives work in RAID-0 at this point? I do the raid part before installing my OS right? Please help with the steps involved from assembling the parts of the PC and then turning it on, to the part of getting the RAID-0 set up between the 2 drives and then installing my windows 7 OS from a Optical drive? Please help, all advice, instructions, tips appreciated as long as on topic. I do not need to be told that this is a bad idea as far as if 1 drive fails I losse it all, I plan on having a disk IMAGE to be able to restore my OS and software to a new set of drives at anytime needed in the event of drive failure. Same goes for lack of TRIM support. Thanks for reading and help =)

• How can I take a one time full backup of a Windows Server without the need for a restore program?

  - by TheCleaner

  I have a Windows SBS server with about 500GB of data that I'm decommissioning but I'd like to take a final backup of the server and place it on an external USB drive. I already have multiple backups of the server on disk from the past but they are through Simpana Commvault. I'd like a backup that will simply copy the file structure, ACLs, timestamps, etc. as is to a NTFS volume on the external drive. This way if someone says "I need x file on the server you decommed" I can search the external drive real quick instead of firing up Commvault, cataloging, restore, etc. I know the built-in Windows backup is great, I just don't feel like running it for a restore job on this. I'd like an option where in the future it won't require a program to run a restore. Rather a simple mount of the drive will suffice. I believe I can use robocopy just fine, but I'm not sure if it will grab the Windows directory, system files, and full user profiles correctly even with the /ZB option. Options? Is Robocopy /E /ZB /COPYALL /DCOPY:DAT /MT:32 /R:5 /W:5 /LOG:copylog.log the way to go here?

• lvm mirroring space unavailable.

  - by Bryan Ward

  I am trying to migrate my data on lvm to two new disks, and setup mirroring between the two. I have successfully migrated all of the data to the first of the two disks, leaving the second one completely available as a mirror. I verified this using pvdisplay -m /dev/sd{g,h}1 --- Physical volume --- PV Name /dev/sdg1 VG Name vg PV Size 931.51 GiB / not usable 3.19 MiB Allocatable yes PE Size 4.00 MiB Total PE 238466 Free PE 82866 Allocated PE 155600 PV UUID v2nc3j-EFBR-QpuG-xgro-Rm59-fmu6-IB3QcR --- Physical Segments --- Physical extent 0 to 49999: Logical volume /dev/vg/videos Logical extents 0 to 49999 Physical extent 50000 to 99999: Logical volume /dev/vg/home Logical extents 0 to 49999 Physical extent 100000 to 129999: Logical volume /dev/vg/music Logical extents 0 to 29999 Physical extent 130000 to 155599: Logical volume /dev/vg/videos Logical extents 50000 to 75599 Physical extent 155600 to 238465: FREE --- Physical volume --- PV Name /dev/sdh1 VG Name vg PV Size 931.51 GiB / not usable 3.19 MiB Allocatable yes PE Size 4.00 MiB Total PE 238466 Free PE 238466 Allocated PE 0 PV UUID LuTrem-WcsZ-qw7l-2CDS-lLKI-wdq0-QEXhLf --- Physical Segments --- Physical extent 0 to 238465: FREE Then when I try to mirror the home logical volume for example, it says that I do not have sufficient space. I used lvconvert -m1 vg/home and the output was: Insufficient suitable allocatable extents for logical volume : 50000 more required Unable to allocate extents for mirror(s). This puzzling to me because it appears as if there is plenty of space on the second disk to mirror. Is there something I have done wrong here? Or is there a way to explicitly tell LVM where to put each leg of the mirror? I'm using lvm2.

• How do I add a WMware ESXi Host to Microsoft Virtual Machine Manager?

  - by user63250

  I am trying to manage virtual machines running on a VMware ESXi host using Microsoft System Center Virtual Machine Manager. I was able to add the ESXi machine using the "Add VMware VirtualCenter server" option, but can't access any of the VMs on the datastore associated with this ESXi server. The datastore of the ESXi box is showing up with the correct name, but it won't let me see any of the VMs that have already been created; I get "There are no virtual machines on this host." Because I couldn't get any of the existing virtual machines to show up, I tried creating some new ones. When using VMM to connect to ESXi and create new VMs, I get the following error messages in the "rating explanation" section: The virtualization software on the selected host does not support virtual hard disks on an IDE bus. and The virtualization software on the host XXXXXX does not support the creation of dynamic virtual hard disk. Any ideas on why I can't manage existing machines and why I can't create new ones? The existing machines were created in vSphere. I should note that the ESXi server and the server running SCVMM are both on the same domain. I should also note that although the ESXi box has been added as a VirtualCetner server, when I try to add it through the "Add Host" option, I get an error message saying "Virtual Machine Manager cannot complete the VirtualCenter action on server EXSi because of the following error: The operation is not supported on the object."

• Ubuntu won't boot from USB memory stick

  - by mackenir

  I used the instructions on this webpage to create a bootable USB drive for running Ubuntu 9.10. Unfortunately it doesn't work on my EeePC. Even with 'Removable Dev.' selected in the BIOS as the first boot device, the PC just boots into Windows 7. How do I troubleshoot this problem? The drive is readable and looks like this: Directory of E:\ 28/10/2009 21:14 <DIR> .disk 28/10/2009 21:14 222 README.diskdefines 28/10/2009 21:14 143 autorun.inf 28/10/2009 21:14 <DIR> casper 28/10/2009 21:14 <DIR> dists 28/10/2009 21:14 <DIR> install 28/10/2009 21:14 <DIR> syslinux 28/10/2009 21:14 4,098 md5sum.txt 28/10/2009 21:14 <DIR> pics 28/10/2009 21:14 <DIR> pool 28/10/2009 21:14 <DIR> preseed 28/10/2009 21:14 0 ubuntu 26/10/2009 16:16 1,468,640 wubi.exe 25/02/2010 00:28 2,147,483,648 casper-rw 8 Dir(s) 5,290,307,584 bytes free

• mkfs Operation Takes Very Long on Linux Software Raid 5

  - by Elmar Weber

  I've set-up a Linux software raid level 5 consisting of 4 * 2 TB disks. The disk array was created with a 64k stripe size and no other configuration parameters. After the initial rebuild I tried to create a filesystem and this step takes very long (about half an hour or more). I tried to create an xfs and ext3 filesystem, both took a long time, with mkfs.ext3 I observed the following behaviour, which might be helpful: writing inode tables runs fast until it reaches 1053 (~ 1 second), then it writes about 50, waits for two seconds, then the next 50 are written (according to the console display) when I try to cancel the operation with Control+C it hangs for half a minute before it is really canceled The performance of the disks individually is very good, I've run bonnie++ on each one separately with write / read values of around 95 / 110MB/s. Even when I run bonnie++ on every drive in parallel the values are only reduced by about 10 MB. So I'm excluding hardware / I/O scheduling in general as a problem source. I tried different configuration parameters for stripe_cache_size and readahead size without success, but I don't think they are that relevant for the file system creation operation. The server details: Linux server 2.6.35-27-generic #48-Ubuntu SMP x86_64 GNU/Linux mdadm - v2.6.7.1 Does anyone has a suggestion on how to further debug this?

• SharePoint, Exchange and Incoming Emails Without Directory Management Services

  - by Nariman

  Trying to keep this as simple as possible. We've already created the email accounts that we need (e.g. account[1-20]@domain.com) on Exchange/AD. We'd like to now enable incoming emails on SharePoint 2007 lists corresponding to these accounts. My thinking is we don’t need to configure Directory Management Services [2] – the architecture will be simpler without it and the application doesn’t require these services. However, we still need to route messages from Exchange to either local SMTP services (via the connector described in the articles below) or by user-specific drop-folder settings (if permitted by Exchange). So the question is: can we instruct Exchange to use a drop folder just for accounts account[1-20]@domain.com? or do we need to change the accounts to account[1-20]@sharepointsmtp.domain.com and re-route those message to the local SMTP service that will drop them on disk? I've read the material below.

• How to handle sh: fetch: command not found

  - by Tyler Johnson

  Okay, I'm a noobie. I know how to build and compose a website, but I have no idea what I'm doing when it comes to servers and server commands, etc. I've recently had a problem with all of my sites on our servers going down all at once and then I have to go in and reboot the server for them to come up again. At first this was annoying, but now it is becoming agonizing as it now takes 3-4 reboots for the websites to come back up. I contacted support for my hosting, but they are not being very helpful. They just keep telling me what the issue might be and basically telling me that I'm going to have to look into it and figure it out, which really isn't possible since I know nothing. Anyway, here are the things they said were possible reasons: They said I have "strange logs" in my Apache webserver log, error: sh: fetch: command not found. My php.ini memory limit is: 256M which is very high. It should be 32M or 64M. Server is reaching Max Clients, meaning we have more than 150 visitors at a time. (They supposedly "fixed" this, but the sites/server are still going down) I have some Wordpress sites with plugins getting errors like: PHP Warning: pack(): Type H: illegal hex digit G in... PHP Fatal error: Cannot use object of type stdClass as array in... PHP Fatal error: Maximum execution time of 30 seconds exceeded in... PHP Fatal error: Call to undefined function file_exists() in... PHP Parse error: syntax error, unexpected '<' I know that's a lot, but I really am at wits end and have no idea what to do now. If anyone could maybe give me some advice or point me in the right direction I would greatly appreciate it! Thanks! Oh, and here are the specs for my server: RAM: 2048MB CPU Shares: 40 Primary Disk: 50GB Data Transfer: 75GB Port Speed: 5Mbps
