Running Dovecot 1.1.3 and after dovecot has been running for awhile it
will just stop authenticating. Only fix is to stop and restart dovecot.
Here is the errors in the logs:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Timo, Thanks. Is there a good rule of thumb of what value I should put in for this? The http://wiki.dovecot.org/MainConfig doesn't talk about this config parameter.
