Hello

restarting dovecot regularly fails with version 2.0.13 on Ubuntu 11.10 due to a running child process exiting after the main dovecot process.

Oct 13 15:04:58 ubuntu dovecot: master: Error: service(anvil): Socket already exists: /var/run/dovecot/anvil Oct 13 15:04:58 ubuntu dovecot: master: Error: service(anvil): Socket already exists: /var/run/dovecot/anvil-auth-penalty Oct 13 15:04:58 ubuntu dovecot: master: Fatal: Failed to start listeners Oct 13 15:04:58 ubuntu kernel: [11132.825253] init: dovecot main process (8668) terminated with status 89

The dovecot/anvil process appears to be the cause of the problem (snapshot of running dovecot processes just after main dovecot process stops):

root 8418 8080 0 15:02 pts/0 00:00:00 stop dovecot root 8419 1 0 15:02 ? 00:00:00 dovecot/anvil root 8422 8420 0 15:02 ? 00:00:00 grep dovecot

This is an Ubuntu specific issue as we use upstart to manage dovecot which monitors the status of the main dovecot process; the Debian init script appears to make provision for this happening.

I can work around this in the upstart configuration but it does look like a potential bug in the sub-process handling in dovecot.

Any help much appreciated - please feel free to comment on https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/873390 as well.
