Some more detail :-)

The previous system (i386) worked fine with dovecot 2.2.2 and pigeonhole 0.4.0 packages also from Atrpms on Fedora 17.

I have downgraded to 2.1.16 and pigeonhole 0.3.5 for the time being.

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 :-(
