Been running dovecot 1.1.2 for about a month now. I Have strange issue
that I have not been able to trouble shoot. What I'm seeing is that
dovecot runs along just fine for about 4 days, and then it will just
stop authenticating everyone (IMAP and POP). No errors in the logs
other than all authentication attempts comes out as password mismatch.
The only fix is to stop and restart dovecot.
% ./dovecot -n

Warning: fd limit 256 is lower than what Dovecot can use under full load
(more than 3072). Either grow the limit or change
login_max_processes_count and max_mail_processes settings

Any ideas on how to trouble shoot what might be going on?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Timo, Thanks I'll give that a shot. As for the Cyrus greeting, if someone is going to try and hack into my system I should at least point them in the wrong direction ;).
