Every 2 or 3 days dovecot will not allow me to log into my IMAP server.
It keeps requesting my username and password. If I do a /etc/init.d/dovecot restart it will start working again for a few days.
I have dovecot set up to use Maildir.

Dovecot Version: Not sure but it is the one that comes with Ubuntu 9.04 OS: Ubuntu 9.04 CPU: x86 Filesystem: Local EXT4 Dovecot Config:

1.1.11: /etc/dovecot/dovecot.conf
