Memory, power, overheating, or perhaps hard drive [controller]
are all possible culprits... assuming that it is indeed hardware.

Define "crash".

You might be able to detect hard drive errors directly in the
kernel logs.  If a random memory error is causing panics, the
console is the place to be.

BSD process accounting might help, but is by no means a magic
silver bullet.  (I also don't recall if it's compiled into the
RaQ kernel by default... I guess I _could_ whip up a program to
test if anyone is interested in this approach...)

Attempting to say "which site or program caused the memory error
or crash" is likely arbitrary and futile:  An unstable system
will often strike randomly, and at the kernel level.

Note that a large compile (kernel, gcc, glibc) with a high number
of max_jobs will often tickle enough things to anger a flaky
system.  If one gets weird errors during such compiles, suspect a
hardware error.

Whatever you do, I'd recommend some console viewing.  Any way to
connect to con while you 1) hunt gremlins or 2) sit back and
watch or log?
