by I'm running pop3 on an isp's server and have noticed some odd behavior
when it gets a little busy, specifically that users trying to log in
and get their mail are defined. I've traced this down (I believe) to
sockets which are opened by popper and seemingly never close. These
sockets hang in FIN_WAIT2 long after the user has retrieved his/her
mail and logged off, and as the timer does not run in this state
(should it?), they are never shut down by the kernel.
Unfortunately, I can't trace the sequence which causes the socket to
be left in this state.
Any ideas?
