As someone else suggested, try adding more swap space. The general rule
is 3 times physical memory.
On a side note, you run mySQL under root? scary...

Sorry. I was in a bit of a hurry when i posted the first message. I
will
provide a bit more info.
The server is a dual Pentium III 450 with 768MB memory and 12GB HD. It
is
running FreeBSD 3.3 with Apache 1.3.9 (mod_php compiled in) and a perl
5.005_03 external interpreter. An important part of both sites is the
UBB
forum, which we will soon replace by a php forum with mysql backend
because
UBB is a giant hog on server resources (especially two of them). The
server
load can become very high especially in the early evening, but as i
mentioned before this seems to be due to the server running out of
swap
space before running out of conventional memory.
This was in /var/log/messages right after the crash (after it had come
up
again of course :)
