<p style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;">Users cannot access to their imap-folders.</p><p style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;">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:</p><p style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;">"Apr 10 15:01:01 mailserv postfix/lmtp[22843]: D64651001D37: to=<<a style="color: #0077cc;" href="https://e.mail.ru/compose?To=user@mailserv.example.com" rel="noopener" data-mce-href="https://e.mail.ru/compose?To=user@mailserv.example.com" data-mce-style="color: #0077cc;" target="_blank">user@mailserv.example.com</a>>, orig_to=<<a style="color: #0077cc;" href="https://e.mail.ru/compose?To=user@example.com" rel="noopener" data-mce-href="https://e.mail.ru/compose?To=user@example.com" data-mce-style="color: #0077cc;" target="_blank">user@example.com</a>>, 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)».<br>It means mail queue increases</p><p style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;">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: <br>"pc-user.example.com [192.168.0.11] user"</p><p style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;">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.
