Thanks to everyone who wrote with suggestions re. my problem. At this point I'm guessing that either the guy who was using the computer for some Web development at the time was killing it with a misbehaving PHP script (he said he found he had an infinite while() loop, though I can't see how that exactly would kill off the whole computer!) or just not enough RAM or swap (it's only got 16 MB, and 32 MB of swap). That doesn't really satisfy me, considering the other problems I've had with this particular machine, but I'll wait and see what other problems may or may not surface in the future, and maybe add a bit more RAM!
