Have encountered some strange behavior of dovecot: after few days of work (5-7 days, ~50 users, imap over ssl or tls) dovecot stops respond with "* OK Dovecot ready.". I.e. connection gets accepted, but no response from dovecot:
[ivan@dyn-226 bin]$ telnet imap 143 Trying 192.168.100.9... Connected to imap.n-ix.com.ua (192.168.100.9). Escape character is '^]'.
It usually means that dovecot-auth isn't responding.
After dovecot restart everything works OK. This behavior we started to observe since rc24, before that on rc9 we didn't see that problem. Currently running on rc26.
Show "dovecot -n" output?
Also when it happens, strace the dovecot-auth process to see what it's doing. http://wiki.dovecot.org/Debugging/ProcessTracing
Or you don't mention anything about logs .. Did you check if it writes anything there? http://wiki.dovecot.org/Logging
