If there's else anything I can do to help track this down, please let me know. It was interesting to see that the errors were coming from the original, rolling replication sync_client process, not a manually initiated sync_client that didn't exit properly. The reason I'm running sync_client manually is to seed the replica with the existing users and mailboxes on the master server, as described in http://www.cyrusimap.org/docs/cyrus-imapd/2.3.16/install-replication.php. Would it be better to use rsync? Is there any reason not to add code to clean up any remaining sync_client processes to the "stop" function in /etc/rc.d/init.d/cyrus-imapd? I am pretty sure we're not using BDB either, but I found a log file, /var/lib/imap/db/log.0000000001, that appears to be a Berkeley DB log file.
