Sounds like a CPU-overheating problem to me. It is well known that
running an inadequately cooled processor at 100% for an extended
period will cause random crashes. There are third-party reports
that it happens with Linux kernel builds, and I have personally seen
it with builds of nhc98 and Hat. When I replaced the CPU fan, the

Non-repeatable crashes certainly point the finger first at hardware
rather than software. Could also be deteriorating memory chips -
but that is likely to bring the whole machine down eventually.
