  • How much memory should my rails stack be consuming?

    - by Hamish
    I am running my own webserver on a 384MB VPS from Slicehost to serve two Ruby on Rails applications on separate Virtual Hosts. I am running Phusion Passenger with Apache2. The following is the contents of my Passenger.conf <IfModule passenger_module> PassengerRoot /opt/ruby-enterprise-1.8.6-20090610/lib/ruby/gems/1.8/gems/passenger-2.2.11 PassengerLogLevel 0 PassengerRuby /usr/local/bin/ruby PassengerUserSwitching on PassengerDefaultUser nobody PassengerMaxPoolSize 3 PassengerMaxInstancesPerApp 2 PassengerPoolIdleTime 300 # Ruby on Rails Options RailsAutoDetect on RailsSpawnMethod smart NameVirtualHost *:80 If i do a 'top' on my server I have 314MB used on average, this seems like too much? Am I mistaken and if not what possible steps can I take to reduce the Memory usage? Thanks!

  • Vmstat indicates memory is disappearing

    - by jimbotron
    I wanted to profile the memory usage of a script. Here's the output before it was running: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 15624 186660 39460 439052 0 0 0 2 1 1 0 0 100 0 Here's the output while the script is running, at the point where free memory was at its lowest value: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 15624 11464 40312 473524 0 0 0 2 1 1 0 0 100 0 So free memory dropped by about 175 MB, and I expected that buff would increase by that amount. But it seems the other columns changed by relatively negligible amounts - how is this possible? Am I interpreting this wrong, or is some memory just not being accounted for in this output?

  • VMware ESXi 4 On-Disk Data Deduplication - possible and supported?

    - by hurikhan77
    Environment: We are running multiple web, database, and application servers which usually share a pretty common installation (gentoo linux) and similar configuration in VMware ESXi 4. The differences are usually only some installed features or differing component versions. To create a new server, I usually choose the most similar (by features) running server, rsync a copy of it into freshly mounted filesystems, run grub, reconfigure and reboot. Problem: Over time this duplicates many on-disk data blocks which probably sums up to several 10's of gigabytes. I suppose if I could use a base system as template with the actual machines based on top of that, only writing changed blocks to some sort of "diff image", performance should improve (increased cache hit rate) and storage efficiency should increase (deduplicated storage space). This would be similar to what ESXi already supports for RAM deduplication (page sharing). Question: Is there any way to easily do this on ESXi 4? I already share the portage tree via NFS but this would not work for the rootfs.

  • Setting up dovecot on OpenBSD

    - by Jonas Byström
    I'm a *nix n00b that just installed dovecot (the selection with no ldap, mysql or pgsql) on OpenBSD 4.0 and I want to set it up for imap use, but I'm having a hard time finding documentation that I can understand. It currently running on port 143 (checked with telnet) but from there I need to do the following: I need some accounts, the once already on the system are fine if I can get those running (seemed to be some dovecot option somehow?), or just adding a few manually is ok too. Was there some setting for this in the default /etc/dovecot.conf? passdb bsdauth {} is uncommented by default... I need to create imap folders, or subfolders. How can I do that? Hopefully not, but anything else I need to do? I want to run without certification validation and no SSL/TLS, would this work by default (client-side settings)?

  • How to Restart Windows Update Service in Windows 7?

    - by N.O.R.G.
    I'm running into an issue with Windows Update on Windows 7 Professional. I am totally up to date in Windows Updates as of last week, but discovered this issue [today] during my Sunday morning PC maintenance ritual. In CONTROL PANEL - SYSTEM & SECURITY - Windows Update, when I select "Check for Updates", I get a pop-up stating: "Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer." I've re-started several times, checked that the service hadn't been disabled at start up, and I've googled extensively on the topic - but have come up with nothing. I know there must be some way to start the service from the cmd line, and I would like to know how to get the service to start at boot. Please let me know if I have left any details out that may aid in formulating a response. Any of the community's excellent insights would be greatly appreciated!

  • Multiple subdomains, SSL on only one using port 80

    - by Emil Flink
    I am running a Apache2 server with three subdomains defined in separate files in /etc/apache2/sites-available I need ONE of those subdomains to be SSL-secured on port 80 for an application to work. Port 80 is required due to circumstances out of my control. The other subdomains are also on port 80. Now, when all subdomains are enabled in Apache the SSL-subdomain is NOT running SSL. If I disable the other subdomains SSL on the SSL-subdomain WORKS. Is there a way to fix this?

  • CA ArcServe r11.1 - have to switch Tape Drive Offline then Online to finish backup

    - by Richard
    Ill keep it brief, I have an HP Ultrium 1 in a server currently running CA ArcServe r11.1. I have 5 daily backup tapes, each of which are new. 3 of the 5 work fine without intervention but 2 of them stop at varying points through the backup asking for a new tape, even though that tape is not full. The way I have found around this is to switch the tape drive offline for 10 minutes then switch it back online, whilst the backup is still running. Has anyone ever seen this before? If so, any ideas how to permanently fix this. If all else fails just some pointers in the right direction. Thanks

  • Adding a Windows Server 2012 Essentials server to an existing domain, without migrating the AD

    - by TiernanO
    I have an existing Active Directory in house, a mix between a Win2K8R2 and Win2K3 domain, and i would like to test out Windows Server 2012 Essentials BETA on the network. When walking though the install, it gives me the option of a new domain, or migrating from an existing domain. when clicking existing, it tells me i can only have one SBS server running on a domain at a time... So, i dont have any existing SBS servers in house (both are full standard or enterprise editions) but i do plan on keeping at least one of these extra servers running... So, how do i get a 2012 Essentials server to join a domain, and not migrate the existing domain? or if i do migrate, can i still get one of the other boxes to act as secondary controllers?

  • Get songs off of Windows iPod and onto a Mac

    - by Justing
    I have been using iTunes on a Dell running Windows XP to sync about 60 gigs of songs with my old school iPod. Well, the Dell's hard drive died the other day, and the only place that I have my music is on the iPod (I do have the CDs, but really don't want to have to re-rip 60 gigs of music). So, now I have a shiny new MacBook Pro. Is there a way to get my songs off of my iPod and onto the MacBook? I googled, and found Senuti. But, I'm leery of accidentally formating the iPod and losing my songs, and I can't tell if it is Snow Leopard compatible yet. Has anyone recently gone through this process? Please provide suggestions for copying songs from an iPod formated to work with Windows onto a MacBook Pro running Snow Leopard. Thanks!

  • Munin fills server memory

    - by danilo
    In the last weeks, it happened several times to me that my vserver (Debian Lenny) was out of RAM (500M) and therefore wasn't able to run apache anymore. When looking at the processes with top, I saw that there were many open munin-limits and munin-cron processes that consumed most of the memory. My guess would be that sometimes Apache temporarily needs more memory, which prevents munin-cron from running. And if munin-cron isn't able to stop itself, it would fill the memory until nothing is left. I don't know whether this guess is true, but could maybe someone know what the problem is and how to prevent it? If necessary I'll remove munin, but I'd prefer to keep it running.

  • Gotomeeting MSI needs elevated privs?

    - by DrZaiusApeLord
    Typically I can deploy MSIs with no issue, but the Gotomeeting one refuses to install. SCE lists it as pending and AD just attempts to install it, gives up, and never tries again. When I tried running it by double-clicking its icon, it told me "needs to run with elevated privs." I don't see how I can get AD or SCE to run it with these higher privs. I can run it by using an elevated command prompt and running msiexec from there. The MSI is the one labeled "GoToMeeting MSI Installer (ZIP)" from here: http://support.citrixonline.com/GoToMeeting/search?search=msi Any ideas? I run an environment where the users are non-admins and would love to be able to upgrade this centrally.

  • How can I open PowerShell via AutoHotkey?

    - by Ryan
    I'm running AutoHotkey 1.0.48.05 on Windows 7. I'd like CTRL-ALT-P to open PowerShell. This is what I have so far: ^!p:: Run %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe Return This is the error I get: File C:\Users[username]\Documents\WindowsPowerShell\profile.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details. I've already set the execution policy to RemoteSigned by opening PowerShell ISE as Administrator and running Set-ExecutionPolicy RemoteSigned.

  • Making internal website available publicly (Win 2008 Server)

    - by endigo
    I have an IIS 7 web site that is running on a Windows 2008 Server (64-bit) VMWare on a Windows 2008 Server (64-bit) Host on my local network. My router is a Firebox XEdge and it has port 80 directed to the IP of the server on VMWare. I can reach the web site from inside the network, but I cannot reach the site from outside the network. I have other web sites that are working through the Firebox, and I am confident that it is configured correctly. I suspect that Windows 2008 server is blocking routed or public addresses, but I have shut down the firewall on the Server that is running on VMWare and the AVG Anti-virus to no avail. How can I make my site available publicly.

  • If I exchange the CPU, must I reinstall the OSes? (swapping cpus from one *nix-like to another)

    - by dag729
    Hi, as suggested by the title, I want to change CPU: actually I have two computers, one with Ubuntu running on an AMD Athlon 64 dual core 5200+ and the other with FreeBSD running on an AMD Sempron single core LE-1250. I would like to swap (I am not sure that this is the correct term...) the CPUs from one computer to the other one, that is take the dual core from the ubuntu pc and put it inside the freebsd pc and viceversa. The mobo is the same. Do you think I will encounter problems?

  • raid 0 data recovery?

    - by Fred
    HI All, I have two identical seagate 7200.9 500Gb drives confiured as a RAID 0 spanned disk in windows. One of the drives has lost power and wont spin up at all. I know this normally means death for the data on both drives but i have a cunning plan.. DISK 1 - NO POWER RAID 0 DISK DISK 2 - FULLY FUNCTIONAL RAID 0 DISK DISK 3 - FULLY FUNCTIONAL SPARE DISK Copy the working drive (disk 2) data to a third 500GB DISK (disk 3), remove the logic board from the working disk (disk 2) and replace it with the non working logic board on the broken drive (disk 1) , then hopefully recreate the RAID 0 with disk 1 and disk 3, just long enough to get the data off it. Hope this makes sense, here are my questions: Windows disk manager atm recognises disk 2 but wont let me access it in anyway, therefore copying the data off it (or getting a disk image) cant be done in windows. Does anyone know of any software (in linux or self booting) that would allow me to access this disk? Anyone know of any software that will recreate the spanned drive off two disk images Am i missing any key information that means i definitely shouldn't even bother starting this, i know its a long shot anyway but its worth a try unless i definitely cant do it. The irritating thing is that i am sure its a logic board failure on disk 1 as it simply wont power up at all, suddenly no signs of life, so i am sure the data is intact! Any help would be really appreciated! Thanks

  • startup Error for Zend Server CE

    - by Jamison
    Hello! I've got a strange startup error for Zend Server CE - it's probably easy to fix, but I don't have much experience with Zend Server! I'm running the latest OSX 10.6.6 and the latest Zend Server CE for Mac. When I run the "start" command from the command line, here is what I get: /usr/local/zend/bin/apachectl start [OK] spawn-fcgi: child spawned successfully: PID: 4206 /usr/local/zend/bin/shell_functions.rc: line 133: 4210 Bus error $WATCHDOG -i $BINARY 1>&3 2>&4 /usr/local/zend/bin/shell_functions.rc: line 133: 4211 Bus error $WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY 1>&3 2>&4 Starting Zend Server GUI [Lighttpd] [FAILED] /usr/local/zend/bin/lighttpdctl.sh: line 46: 4212 Bus error $WATCHDOG -i $BINARY Starting MySQL SUCCESS! /usr/local/zend/bin/shell_functions.rc: line 133: 4304 Bus error $WATCHDOG -i $BINARY 1>&3 2>&4 /usr/local/zend/bin/shell_functions.rc: line 133: 4425 Bus error $WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY 1>&3 2>&4 Starting Java bridge [FAILED] /usr/local/zend/bin/java_bridge.sh: line 39: 4426 Bus error $WATCHDOG -i $BINARY Zend Server started... The challenge is that ZEND SERVER wont open the GUI with this error, and seemingly I can click on Zend Server in the Applications folder and it opens for a second and immediately closes. I've made sure that Web Sharing is turned off to avoid conflicts, and I've run Disk Utility from my recovery disk to make sure there are no file system errors. Here is what the lines that are referenced in the errors have in terms of code: shell_functions.rc: (starting on line 132 - the error message says line 133...): launch() { if [ -z "$DEBUG" ]; then exec 3>/dev/null 4>&3 else exec 3>&1 4>&2 fi $WATCHDOG -i $BINARY 1>&3 2>&4 RET=$? if [ $RET -eq 0 ];then $ECHO_CMD "$BINARY watchdog is up and running.. ${OK_COLOR}[OK]${T_RESET}" return $RET else #$WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY >> "$PREFIX/logs/watchdog_$BINARY.log" 2>&1 $WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY 1>&3 2>&4 report $?

  • Empty sshd_config file

    - by Thomas
    I run a Centos 5 server with a LAMP stack. I was told this morning that the server was down not serving web content. I then tried to restart httpd but it failed due to another process was listening on port 443. I checked what process was running on 443 using netstat and it was sshd. I then checked the sshd_config file to check the ports that sshd was running on but the sshd_config file was completely blank. I than ran chkrootkit and it flagged not suspicions. What could of caused the sshd_config file to be blank, and sshd service to be restarted? I would really value your thoughts. All the best.

    Using 7 build 7600. Wen I try to open a command window, I just get returned to my previous folder/desktop. If I try to open an extended window I get to the UAC, answer yes and again am returned.

My video adapter is GeForce 7600 and I have no other known problems at this time. Thanks in advance.

  • Mysql innoDB corruption after server crash

    - by Ward Loockx
    Yesterday my server died because an outage in the data center. Today it's back up, but having some problems with mysql. First of all my mysql server was not able to start. For this reason I deleted the files ib_logfile0 and ib_logfile1 in /var/lib/mysql folder (I still have the old failing files). After this my server was able to startup again. But now I see a lot of issues in the mysql log file. Sep 1 09:43:55 * mysqld: 120901 9:43:55 InnoDB: Error: page 70944 log sequence number 8 1483471899 Sep 1 09:43:55 * mysqld: InnoDB: is in the future! Current system log sequence number 5 612394935. Sep 1 09:43:55 * mysqld: InnoDB: Your database may be corrupt or you may have copied the InnoDB Sep 1 09:43:55 * mysqld: InnoDB: tablespace but not the InnoDB log files. See Sep 1 09:43:55 * mysqld: InnoDB: http://dev.mysql.com/doc/refman/5.1/en/forcing-recovery.html When I check the docs on mysql.com, I found that I need to recover my database with backups. I have a backup but not sure what's the good way on importing it. Or is there a way to recover without having to re-import the database again? So if I'm correct I need to put innodb_force_recovery to 4 in mysql and delete all current data and re-import? Is there a way to do this without having downtime? I also have one slave running. This slave has the current status now: Last_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave. How can I totally reset the slave after the new import on the master has happend? Hopefully we can find a solution without not to much downtime. Thanks!

  • Apply Group Policy to Remote Desktop Services users but not when they log on to their local system

    - by Kevin Murray
    Running Windows Server 2008 Service Pack 2 with Remote Desktop Services role. I want to hide the servers drives using a GPO, but not the users local drives when they are logged on to their local system. Using a GPO, I went to "User Configuration - Policies - Administrative Template - Windows Components - Windows Explorer" and enabled "Hide these specified drives in My Computer" and "Prevent access to drives from My Computer" and in both used "Restrict all drives". Then under "Security Filtering" for the GPO, I restricted it to the system running Remote Desktop Services and the specific users who will be using RDS. I then applied the GPO to our domain and it worked a little too well. Not only was I successful in getting the GPO to work for RDS users, but it also affected those same users at their local systems as well. I've tried everything I can think of, but can't figure out how to apply this just to the RDS but not at their local system. What am I missing?

  • Drupal on IIS 7 (PHP FastCGI) produces blank every 1 hr

    Hi, I have Drupal running on IIS 7 with PHP Fast CGI installed. The FastCGI setting: http://img709.imageshack.us/img709/1748/fastcgisetting.jpg hxxp://img404.imageshack.us/img404/5837/fastcgisetting2.jpg I have Drupal running on isolated AppPool with default setting when I created the AppPool: hxxp://img716.imageshack.us/img716/5444/fastcgisetting3.jpg The problem is that after 1 hr or so If I browse to hxxp://localhost , there's nothing but only the blank page until IIS 7 is restarted. I think this has to do with PHP Process Recycling Behavior or other things that I'm not sure about. Can you show what's the cause of the problem?
