Any kind of load level/history. A kernel >config? This machine is a shell server, with a bunch of IRC processes on it. Minimal hosting. (just user pages, server/~foo) I attached my kernel config, if this would help anyone out. If it's up long enough, pretty high load. Once people get a chance to get their processes back up, around 400-500 processes. The machine can handle this though, it's a dual 550 MHz, with 768 MB ram. > >Does the machine completely drop its keyboard too? You might Yep - totally locked up.

If this is relevant, a few days ago the box crashed and it was scrolling errors related to microuptime() (I can post these if relevant) and someone suggested that APM was causing that, which had never been compiled in this box's kernels. If nobody has any other ideas, I guess I'll replace the cooling fans. I'll also check out the BIOS and make sure APM-type stuff is disabled.
