We have a few users experiencing locking problem. When starting Thunderbird, there is no new emails in Inbox. Dovecot createa a lock file /var/spool/mail/<user>.lock. It never completes openning Inbox. If closing the mail client, the open imap session does not get closed, nor the lock file get deleted.
What is the process doing? Check with "strace -p <imap process pid>"? How large is the user's mailbox?
The size of inbox varies. Some is large, some are only a few hundred KB. If the mailbox is large, it may take time to re-generate index and put lock on inbox file until it's done. However, it should not for smaller mailbox file.
Are you using pop3? Do you have pop3_lock_session=yes? Other than that I can't think of anything that could keep the lock file for a long time. So strace would be helpful.
