when there are too many new messages in INBOX  (about 4000 new messages) ,  I can't open INBOX by webmail to check new e-mails . 
at the same time there is a lock file named dovecot-uidlist.lock still in maildir directory . I have never see this file ,I guess dovecot-uidlist is locked by dovecot-uidlist.lock and no longre unlocked so dovecot-uidlist can't be operation then I unable to access mailbox. this is my guess , dovecot-uidlist.lock appears under what conditions?
