dovecot - Jan 2007 - periodic problems with dovecot-1.0rc19 (No authentication sockets found)

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,

	-mi

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.

It means that something wiped out the sockets from Dovecot's login_dir
(/var/run/dovecot/login or something).

Wonder if there's some cronjob going through the files and deleting
them? That's pretty much the only thing I can think of.

Earlier Dovecot versions also deleted the sockets when using "dovecot
-n" or -a, but that was fixed in rc16.
