Mysterious process hangups
My suitemate has a dual-core Opteron (not dual dual-core, just dual-core) in a Tyan Thunder K8S Pro 2882 motherboard. We're running Gentoo AMD64 on it, kernel 2.6.12 (w/ SMP, of course), gentoo patchlevel r9.
Every now and then, we'll experience process hangups. The process still responds to SIGINT, SIGTERM, and SIGKILL. (It may very well respond to all signals, but those are the only ones I've empirically tested, and I don't think I know enough about the Linux kernel signaling architecture to make any generalizations.)
The hangups seem to occur most frequently when both cores are under heavy load: for example, compiling gcc while both cores are also running a Yafray render.
I'd provide system logs, except that I don't have any to provide -- I've only recently noticed these, and haven't logged anything. When I come across the problem again, I'll capture all the data I can...
Any ideas? I know what I've given is quite vague, but anything to look into would be welcomed.
