[Dovecot] periodic problems with dovecot-1.0rc19 (No authentication sockets found)

[Mikhail Teterin]

Hi, Timo!

On the new server running 1.0rc19 people stop being able to login every once 
in a while. The log messages on the server side are:

Jan 30 12:18:50 bonkers dovecot: pop3-login: No authentication sockets found
Jan 30 12:18:50 bonkers dovecot: pop3-login: No authentication sockets found
Jan 30 12:18:59 bonkers dovecot: pop3-login: No authentication sockets found
Jan 30 12:19:01 bonkers dovecot: imap-login: No authentication sockets found
Jan 30 12:19:06 bonkers dovecot: pop3-login: No authentication sockets found

Restarting dovecot helps for a while, but then the problem reappears...

The config-file was copied from an older server running 1.0.r15, where we 
never saw this problem...

The old server ran FreeBSD-4.10/i386. The new one runs FreeBSD-6.2/amd64.

Thanks for any hints! Yours,
