pop3-login segfaulting

[James Shewey]

I upgraded dovecot from v1 to v2 as part of a CentOS upgrade (5.6->6.5) and am now running on 2.0.9. Any time I connect to the pop or imap ports however I get "master: Error: service(imap-login): child 2860 killed with signal 11 (core not dumped - add -D parameter to service imap-login { executable }" after following the core dump instructions at http://www.dovecot.org/bugreport.html.

The problem is that I'm not sure how these processes are spawned in order to add the switch. Can I spawn them directly? If so, I ought to be able to do an strace to track down the issue as well.

You should upgrade to a more recent version, debugging 2.0.9 makes less
sense

This was solved by upgrading my config file using "doveconf -n -c /etc/dovecot/dovecot.conf > dovecot-2.conf" The other problem I was running into was my dovecot.conf file was getting changed to a symlink to itself and I was getting an error " Fatal: Error reading configuration: read(/opt/dovecot/config) failed: Connection reset by peer. This was resolved by changing the base_dir = to an empty directory that did not contain dovecot.conf.
