[Dovecot] Dovecot 1.0rc7 quits without notice

[Chris Laif]

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.

The above described scenario has been observed 2 times.

Any suggestions are welcome.
