Just for kicks, try rebooting. I'm running a large site and have been
chasing a very intermittent pop3d gremlin that causes pop3d to hardlock
while all other services are fine. only thing that clears it is a complete
reboot. we can go for months without a single one, then have three in a
i can't find a single bit of reason or logic for it. i'm hoping one of
these times i'll catch it with some time to look at it in gdb. but last
time i tried it under gdb it worked fine -- but only the process under gdb
