Dovecot v1.1.alpha4 imap after some time stops responding. It can not be restarted as /etc/init.d/dovecot restart
killall imap also does not help
killall -9 imap and then restart does help
in log I see message (repeted periodically) that Sep 12 09:50:02 localhost postfix/local[22533]: C7057753B6: to=username@domain , relay=local, delay=5195, delays=5156/0.01/0/39, dsn=4.2.0, status=deferr ed (cannot update mailbox /home/username/Mailbox for user username. unable to lo ck for exclusive access: Resource temporarily unavailable)
lsof -n shows that the file is is open by imap process.
