Today I switched one of our servers from Courier (deployed 3-4y ago) to DCrc7. Everything seemed very nice (system load dropped significantly).
Unfortunately after some time and ~8000 pop3-logins the main DC loop just quit without _any_ notice. Some pop3-login childs still showed up in the processlist, but the main listener on port 110 was gone.
Apparently it crashed. Getting a backtrace would help. Do you see a core file in /var/run/dovecot? If not, make sure you have "ulimit -c unlimited" before starting dovecot. Or I guess you could also run gdb directly:
gdb dovecot run -F <wait for crash> bt full
Although the pop3-login processes should have gone away if the dovecot master process had died.
I observed another unexpected shutdown this morning, but this time (!) the error
Login process died too early - shutting down
showed up in the logs. I'm using simple passwd-file and userdb-static auth. The passwd file has not been changed during the night.
This _may_ be related to http://www.dovecot.org/list/dovecot/2006-August/015660.html (?).
I'm closely monitoring the system (now with 'ulimit -c unlimited') and will report back if there are any news.
