Out of memory errors
Hi. I've installed ISPConfig 3.0.0.8 RC1 on a Ubuntu 8.04 256Mb server, which worked fine. However, after a couple of days I noticed that my server was down. I rebooted and I just noticed (about 2 days after reboot), lots of these fellows:
Code:
[ 4186.930413] Out of memory: kill process 3774 (mysqld_safe) score 154236 or a child
[ 4186.930555] Killed process 3816 (mysqld)

Any help very much appreciated.

I had to do another reboot because it crashed again. Right after reboot I did a 'free -m':
Code:
total used free shared buffers cached
Mem: 256 252 3 0 1 18
-/+ buffers/cache: 232 23
Swap: 511 59 452
Not much left is there? I'm not sure what the ISPConfig specs are concerning memory but I figured that 256M should be sufficient for a simple server running a couple of minor sites...

ISPConfig has no extra specs for memory usage as ispconfig itself does not use much memory, maybe about 20 - 30 MB.

That depends on the usage of the sites. 256 is really low and as you see you are getting out of memory errors, so its too low for your current setup. Does your server ahs a swap file or is it a vserver so no swap is allowed?

Hi. This is htop's output right after a not so graceful reboot. I've also noticed that CPU usage is increasing over time. Currently it takes about 3 hours or so for the machine to consume up to +100%, which makes it unresponsive.
I currently have only one site running on this configuration which is nothing more than just a holding page.
Code:
3 [|||||| 18.7%] Uptime: 00:01:43
4 [||||||| 20.1%]

I've tried stopping daemon by daemon see what the results would be. Stopping MySQL, Apache and Postfix doesn't do much. However, when I killed off ClamAV I noticed over a 100Mb in memory drop. I can't seem to figure out how to stop the ISPConfig server however. Any idea's?
Thanks,
Luke
PS: This machine is a clean Ubuntu Hardy running at slicehost.com. I've followed the instructions on this page to set it up. I've added nothing else myself (except htop for CPU/mem info): http://www.ispconfig.org/docs/INSTALL_UBUNTU_8.04.txt

Hi. Sorry, I can't check any longer because I dumped the slice. If letting it alone after a reboot it would in the span of a day or so, go all the way up the 100% CPU usage. Unless I would set up an automatic reboot, it would be to much work.
The contents of my.cnf would be that of what I would get through the installation process since I've haven't touched it. Maybe the default values of it have recently changed? I dunno...
I will try to run the same installation in a virtual machine, see if I can reproduce the issue in that environment...

In my case, I can solve this issue changing MaxClients from 150 to 20 on apache2.conf
