dovecot - Jun 2011 - segfault in dovecot 2.0.9

Hi folks,

I noticed the following in the dovecot log files:

/var/log/maillog

Jun  9 00:12:34 mail dovecot: master: Error: service(imap): child 8970 
killed with signal 11 (core dumps disabled)
Jun  9 00:12:34 mail dovecot: imap-login: Login: user=<username>, 
method=PLAIN, rip=IP, lip=IP, mpid=8987, TLS
Jun  9 00:12:34 mail dovecot: master: Error: service(imap): child 8987 
killed with signal 11 (core dumps disabled)

/var/log/messages

Jun  9 00:12:34 mail kernel: imap[8970]: segfault at 0 ip

# dovecot -n
# 2.0.9: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-71.29.1.el6.x86_64

OS: Scientific Linux 6.0 (Red Hat Enterprise Linux 6.0)
Filesystem: ext4

I think this is a bug. Any ideas?

Best regards,

Morten

There's really no way to know why this happens without a gdb backtrace.

It's also possible that it has already been fixed in newer versions.
