The problem persists with mbox inbox folders in v1.1.alpha4. I get a stalled process "imap" which can not be killed by killall imap only by killall -9 imap This process takes a lock of user mailbox thus prevents the user to read/send mail. Other users are OK

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

lsof -n shows that the file is is open by imap process.
