Users cannot access to their imap-folders. Sometimes (once or twice a week) users complains that they cannot connect to their mailboxes and read emails. At the same time I see such records in maillog: "Apr 10 15:01:01 mailserv postfix/lmtp[22843]: D64651001D37: to=< u...@mailserv.example.com >, orig_to=< u...@example.com >, relay=mailserv.example.com[/var/lib/imap/socket/lmtp], delay=300, delays=0.13/0/0/300, dsn=4.4.2, status=deferred (conversation with mailserv.example.com[/var/lib/imap/socket/lmtp] timed out while sending MAIL FROM)». It means mail queue increases Also I find out lots of "PID-files" in /dev/shm/cyrus-imapd/proc which don't contain info of linked imap-folder. For example: "pc-user.example.com [192.168.0.11] user" It's unhealthy situation and I don't understannd what reason is. In order to help users I just kill their IMAP-process and make reconstruct mailbox. Please help me with investigation of the problems.
