Hi, We have a server which locks up about once a week (for the past 3 weeks now), without any warning, and the only way to recover it, is to reset the server. This causes unwanted downtime, and often software loss as well. How do I debug the server, which runs CentOS 5.2 to see why it locks up? The CPU is an Intel Q9300 Core 2 Quad, with 8 GB RAM, on an Intel Motherboard The last few entries

Hi, I have a problematic CentOS XEN server and hope someone could point me in the right direction to optimize it a bit. The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD. dom0 is set to 512MB limit with a few small XEM VM's running: root at zaxen01:[~]$ xm list Name ID

Hi, My firefox (Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.6) Gecko/20091216 Fedora/3.5.6-1.fc11 Firefox/3.5.6) on Gnome 2.26.3 will randomly crash, without any errors. /var/log/messages & /var/log/Xorg.0.log doesn't show anything that caused any errors. And it doesn't matter on which website(s) I'm busy with, it will just crash. Does anyone know how to check for a

Hi, I want to setup a central installation server, but haven't done this before, so I want to find out what would be best practices for this? The server I have already runs as a central repo, which is updated from one or our local centos mirrors, and the other CentOS servers (both i386 & x64), as well as CentOS VPS's get their updates from this server. But, now I want to allow a

Hi all, I hope someone can help with this one. On one of our VPS's we have a fairly large MySQL database, which gives me the following error when running some queries against it: An error occured!Can't execute statement: Error writing file '/tmp/MYL4qeT5' (Errcode: 28) SQL: , , select * from tips order by rand() limit 0, 1 , According to google search, errorcode 28 means

I've just spent at least half an hour swapping files, downloading things and stuffing around with memtest86 and memtest86+. I can't get either to start from pxelinux. Currently I have "memtest86" as the filename, and i'm trying to load it direct (not trying to use memdisk or anything). This just results in a near instant reboot. Am I doing something wrong? I can't

Dear Colleagues, memtest86 does not work any more after upgrading PXELINUX to 6.01. When trying to boot, I get the following message: PXELINUX 6.01 2013-07-04 Copyright (C) 1994-2013 H. Peter Anvin et al Loading memtest86... ok Booting kernel failed: invalid argument boot: The config is simple: DEFAULT memtest label memtest kernel memtest86 Any ideas? What additional information can I

Hello list, any try the new memtest86 v3.2 with isolinux 3.11 cd and pxeboot? How is the proper way to chainload memtest86 I was tried: label memtest kernel memtest.bin but, nothing happens just a weird hang (my older versions of memtest hangs too). Anyway chainloading in a floppy image with memdisk on CD or pxeboot was fine but if I use memory to emulate a floppy I was not using this memory

Hi! At first thanks for your great work! I started to make multiboot CDs 1,5 years ago, with Bart Lagerweij 's utils. I have a problem with the memtest86 floppy image, made by the authors in the .zip file, downloadable from it's homepage, when I use diskemu. Some days ago I found on Bart's page a new method to select boot images on CD with syslinux/isolinux/memdisk. I thought this is

Greetings. Every couple of day's I have a web server running CentOS 4.1 with all the patches as of Saturday that is crashing every couple of day's. Usualy between 4-6 am. The Console shows: Double Fault gdt at xxxx memory Double Falut tss at xxxx memory On reboot all is fine. It's running apache and DNS no SSH access. It passes memory test Memtest86. I can provide more

Hi all, installed the old space shooter Swarm and it is running fine pleased to say except artefacts of lasers and rockets that have been fired staying on screen for up to another 6 seconds. This is as you can imagine a bit irritating as they move with and stay on the screen. Wine x.19. Have set the game to 'unmanaged' by the window manager as was suggested here in another thread, but

Hi, I'm considering buying a QNAP TS-212 NAS and I wonder if this device is powerful enough to run dovecot too (there is a pre-built dovecot package available from QNAP)? The main goal would be that my mail is stored centralized on the NAS, where I can access it from multiple systems without ending up with mail scattered over each system (which is exactly what is happening now due to the

Hi All, So I''m using scriptaculous in rails to allow opening and closing of messages in a threaded forum without the need for reloading the entire page. What I was wondering was if there was some way to store the state (which messages are open and which are closed) in a cookie or something, so that when the user does reload the page the messages won''t all be reset to their

Hi guys! I tried to boot memtest86+ v4.2 (renamed memtest.bin to memtest), and i have issues to boot it with pxelinux 5.x and greater.Pxelinux 4.06 works fine both memtest 4.1 and 4.2. With version 6.00 no error message caught, only writes out dots. Any keypress does a reboot.With version 5.01 the error message is the follow:Loading images/memtest/memtest86... okBooting kernel failed: Bad file

Hi! I am currently trying upgrade my bios pxe server with additional uefi support. My current using memtest86+ doesn't seem to support uefi, so I would have to use memtest86, as it supports this. But the memtest86 file itself is an *.efi file. When booting this one directly without syslinux, its working. But I want to launch it later from the syslinux menu. Can I chainload somehow another

Hi, So I'm going to be upfront about this: I don't know how to fix this problem or even who to talk to. I've tried the JK community, #winehq, #ati, and even the ATI forums, but no there was help to be offered. Here's the problem... Playing Jedi Knight: Dark Forces II (http://appdb.winehq.org/objectManager.php?sClass=application&iId=122) on Wine, I get such horrid framerates

Hi tody I tried to compile the source an downloaded the two folders asterisk and libpri from the CVS tree into /usr/src. Then I changed the path to the libpri and made make clean; make install. Everything worked fine. After that I changed the path to /usr/src/asterisk and made also make clean and make install. After some time I got an error: ..... SYDETECT_MARTIN -DNEW_PRI_HANGUP -c -o
