I have a dedicated server that I recently upgraded from fedora core 1 to fedora core 2. Its now using kernel 2.6.9-1 and everything seemed ok. Yesterday when I tried visiting my website it failed on a lookup. After logging into my machine I found that the services named and mysqld were shutdown by the kernel's oom.

The machine that i run is stand alone box running named, mysqld, sshd and apache. I don't run other services, I'm not rooted and I'm the only user that logs in. Before I upgraded I did not run into this problem.

Does anyone have any advise on configuring the kernel's memory manager or even on how to disable this?

Are you sure your box is not hacked? Anything suspicious in logs?
