hi,
I have serious problem with my cyrus21 (debian sarge 2.1.18-1) - I have
hundreds of connectin in CLOSE_WAIT state.
I can telnet to port 110 , but sometimes I can't even get the banner of the
service.
I tried to increase maxchild (now -1 - unlimited), I tried babysit,
increasing maxfds up to 2000 etc, but it still doesn't kick out the
CLOSE_WAIT state connections. Any suggestion?
Thank you

I don't run POP here, but you might search the mailing list archives for
information about running out of entropy for POP (using /dev/urandom
instead of /dev/random). If I remember correctly, each POP connection
requires a certain amount of entropy from /dev/random. When you run out
of available entropy, POP will hang waiting for more.
The list archives should have some more information, or hopefully someone
else can chime in. :)
