AOOI Installer swap/oom-killer issue
Posted: Wed Feb 18, 2009 12:25 am
Good day,
I was running centos4.7 installed from one of your earlier aooi installers think it put 4.3 on originally but through upgrades finished at 4.7. Anyways had a few issues with the raid on it and oom-killer. I completed a backup of the server and tried to run the aooi installer to put the system upto centos 5. But the installer complained about lilo. So i reimaged the server then used the aooi to install centos 5. did all the updates and installed plesk 9.0.1 then went through and restored all my sites ( Only 7 domains running on the server). For a couple days everything seemed alright but then started getting oom killer again. I don't know much about this i'm learning as I go here. But it seems to me something is messed up with the partitioning. For 1 I don't think swap is set right. When I do a free -m i see the following:
Also doing a cat /proc/mdstat provides the following output:
And fdisk -l shows the following:
The following is my /etc/fstab:
I think the swap issue is whats causing the oom-killer but like I said I'm still learning here. What ever it is I have to get it sorted as its taken down the server a couple times a day and i have to reboot the server from the 1and1 admin panel as it locks right up.
Any help you can give me on this will greatly be appreciated.
