Hi,
I am seeing constant "Log synchronization error"s in my logs. See later for an example.
This is dovecot 2.2.4, pigeonhole 0.4.1, and postfix 2.10.1 (with mailbox_command = /usr/libexec/dovecot/deliver) on a Fedora 19 system.
I am using packages from Atrpms so there are some patches applied - ask for details. The mailboxes have resently been moved from a i386 system. I have tried to manually do "doveadm force-resync" for all users, but the problem persists :-(
Here are an example from a user which does not use sieve: 11:45:48 Y dovecot: imap-login: Login: user=<X>, method=PLAIN, rip=62.199.61.123, lip=192.168.0.5, mpid=21531, TLS, session=<XxDNm3XhdAA+xz17> 11:45:52 Y dovecot: imap-login: Login: user=<X>, method=PLAIN, rip=62.199.61.123, lip=192.168.0.5, mpid=21541, TLS, session=<UewQnHXhAwA+xz17> 11:45:54 Y dovecot: imap(X): Error: mdbox /var/mail/X/mdbox/mailboxes/INBOX/Streams/dbox-Mails: map uidvalidity mismatch (0 vs 1283330954) 11:45:54 Y dovecot: imap(X): Disconnected: Internal error occurred.
