dovecot - Mar 2011 - Error: write(auth socket) failed: Broken pipe

Hello
>From time to time I'm seeing errors like this in my logs:
Mar 16 10:45:55 box5 dovecot: lmtp(5438): Error: write(auth socket)
failed: Broken pipe

This causes delivery from postfix to fail until I restart dovecot.

There doesn't seem to be any other messages in the logs related to this
error. Has anyone ever seen this error?

Thanks
Andre

Yes. We've seen on occasions when the network connectivity between the
auth db and dovecot breaks (due to a network problem).

This would mean that the auth process got lost. That shouldn't normally
happen.. Maybe it crashed?

http://hg.dovecot.org/dovecot-2.0/rev/7d9db422549a should help with
this.
