We are running Dovecot 1.0-rc27 and have run across what seems to be a
fatal error (SIGSEGV) in the past few days (4 times total in past 6 days).
It appears to have been 5 separate users, 5 separate remote IP addresses.
Two of these have this format:
Mar 26 15:13:10 myhostname dovecot: imap-login: Authenticate PLAIN failed: Don't send unrequested data: user=<rmtuser>, method=PLAIN, rip=10.9.9.9, lip=10.1.1.1, TLS
The other three have this format:
Mar 26 09:41:45 myhostname dovecot: imap-login: Authenticate PLAIN failed: Don't send unrequested data: method=PLAIN, rip=10.9.9.9, lip=10.1.1.1, TLS
Here's the first one a bit more expanded, showing the SIGSEGV (signal 11):
Mar 26 15:13:10 myhostname dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=10.1.1.1 rip=10.9.9.9

Mar 26 15:13:10 myhostname dovecot: imap-login: Disconnected: user=<rmtuser>, method=PLAIN, rip=10.9.9.9, lip=10.1.1.1, TLS
Mar 26 15:13:10 myhostname dovecot: child 3333 (login) killed with signal 11
What can I do to further diagnose this problem?
