Yes, I've seen some segfaults which coincided with such errors as well. It happened for me when I sent a message which was aliased off to 100 or so accounts. I haven't been able to troubleshoot it further yet, though.

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,
