Aug 19, 2008I have a company offering me the follow:
Core 2 Quad Q6600 Processor
1 GB RAM
250 GB Hard Drive
500 GB Bandwidth
5 Usable IPs
Free Cpanel
The issue here is that they're not real dedicated servers, they're Openvz Dedicated Kernel with Quad Core CPU. The question I have is does anyone have any experience with openvz servers and how does the performance add up compare to dedicated servers? The hosting company says they do it this way because they get cpanel licenses cheap so can give it away for free. Any thoughts?
Kernel Panic ...
Nov 1, 2008I just got 2 'kernel panic' crashes in a row (about 1 hr between them). During that time
I cannot access ssh, I need to contact the datacenter for manual reboot.
I checked logs, and I cannot see anything abnormal. I am also not sure what I should be looking for.
I'm really scarred that this is going to keep hapening.
I actually may have found something in logs:
Nov 1 13:20:43 punky kernel: audit(:0): major=252 name_count=0: freeing multiple contexts (1)
lov 1 13:20:43 punky kernel: audit(:0): major=316 name_count=0: freeing multiple contexts (2)
lov 1 13:20:50 punky pure-ftpd: (shont@84.201.220.8) [INFO] Logout.
Nov 1 13:45:04 punky syslogd 1.4.1: restart.
But I still don't know what this means.
I use CentOS.

Feb 4, 2007Yesterday one server drops, and after a reboot request, my datacenter said that was because a kernel panic.
After the reboot, the server is online, but i need to figure out exactly what happened.
So I try to look on /var/log, but I couldnt find anything.
Which files exactly should I look for? messages? dmesg?
Kernel Panic
Aug 20, 2007I have upgraded to kernel 2.6.16.X and when I boot, it is showing as kernel panic message.
Kernel Panic - not syncing: Attemted to kill init!
Is it the standard messages? How can I debug? Is there any dump file to trace the problem?

Rescue Cd - Kernel Panic
Apr 11, 2008I have a hard drive installed with CentOS 5 before.
Now the hard drive had crash (kernel panic)
I insert in Fedora rescue cd and succesfully booted and it mount under /mnt/sysimage
The question is how do I get into the hard drive? I just need to copy 2 files inside my home directory
I cannot see any sdb or anything like that /dev except for sda1~sda15 which I believe is the rescue cd image
#df
/dev /dev
/tmp/loop0 /mnt/runtime
/dev/sda2 /mnt/sysimage
/dev/sda1 /mnt/sysimage/boot
/dev/sda5 /mnt/sysimage/tmp
/dev /mnt/sysimage/dev

Server Goes Down With Kernel Panic
Nov 24, 2007I have a cpanel server which goes down with a kernel panic.
In the messages files, i could find the below lines.
The kernel in the server is 2.6.9-55.0.12.ELsmp #1 SMP
h/w is 4 cpu Dual Core AMD Opteron(tm) Processor 265
Is this a kernel bug?
If yes , how can i solve it?

Server Crashed: Kernel Panic
Mar 23, 2007Today my server just crashed instantly... It was running fine with a load of 0.12 but then it went down all the sudden. After a reboot I checked the /var/log/messages file and saw this:

So it seems like httpd crashed my server? I checked the Apache error_log and noticed lines like these:
Code:
*** glibc detected *** free(): invalid pointer: 0x08872c98 ***
[Fri Mar 23 15:57:03 2007] [error] [client x.x.x.x] Premature end of script headers: /home/user/public_html/forum/index.php
[Fri Mar 23 15:57:03 2007] [error] [client x.x.x.x] File does not exist: /home/user/public_html/500.shtml
When I look at the whole error_log it seems like such errors appear frequently and for different websites and PHP applications. This isn't the only glibc error, there's also stuff like "*** glibc detected *** corrupted double-linked list: 0x088e0bb8 ***". I have recently installed eAccelerator and searched the web: I'm not the only one who has such problems with eAccelerator. Do you think these glibc errors may have caused the server to crash?
Also, lately I noticed a lot of lines like these in the /var/log/messages file:
Code:
Mar 23 15:47:45 alpha kernel: post_create: setxattr failed, rc=122 (dev=sda7 ino=4318565)
and
Code:
Mar 23 15:50:56 alpha ntpd[2958]: sendto(66.111.46.200): Operation not permitted
I've done some Google'ing on the first error and it seems like someone with the same error got it fixed by running a filesystem check... By the way /dev/sda7 is my /home directory. But in order to run a filesystem check I need to disable all services and unmount /home? That's kind of a pain in the ***... In general, how long do you think it takes to run a filesystem check? Here's information about my /home partition:
Code:
/dev/sda7 198G 71G 118G 38% /home
Kernal Upgrade + Centos Upgrade
Feb 24, 2007I have a server running cPanel.
At the moment, I am been hosted on an unmanaged server (dedicated).
My server provider is offering $25/hour for managed support.
My Kernal and Centos have not been updated for a while and I am looking to upgrade both of them. I am wondering how long would these 2 jobs normally take?
