[Dovecot] Dovecot hangs after 2 or 3 days

Hi all,

We've some problems with our dovecot installation, its the latest stable compiled on a debian woody box.

After 2 or 3 days dovecot hangs, no user can login (pop3 and imap), there's nothing in the logs. The client does allways timeout, if I restart dovecot all works well again.

It's a box with s.th. around 400 users, we've enough mem free, load is not a problem, it went from 0.9 to 0.1 after migrating from cyrus-imapd, so this doesn't seem to be hardware related.

My dovecot conf is online at: http://mail.sunday.de/dovecot.conf

best regards/Mit freundlichen Grüßen Jens Gutzeit
