A FBSD 4.7 server this morning locked up and when I got to the data center I
found a bunch of IO error messages saying the pager couldn't allocate needed
swap space (or something close to that). Unfortunately these messages didn't
get logged anywhere that I could find and I didn't have anything on me to
write them down. The server has 500mb ram and is usually using about 70% of
that. The server didn't panic, but the console was not responsive so I had
to do a cold reboot. Everything came back up fine.
Any ideas on how to debug this further? This server has run with the same
configuration (apache/zope/mysql/qmail) for about 2 years without any
issues. If something did actually use up all the swap, would what happened
be normal behavior?
