My server goes down from time to time. When it does, it is still on

it down. I've wondered if it was a bad hard drive in the RAID, but
after looking at the Apache logs just now and seeing a plethora of
memory leak notices, I'm wondering if it's a memory issue. Would a
bad script that is leaking memory cause the machine to run out of
memory and then freeze up or cause all of the services to become
non-responsive?

the kernel's OOM killer, but it can't kill the network stack unless
there's also a kernel or hardware bug.

No. A program that simply eats memory can cause thrashing and activate
