If it happens with you all the time, could you try:
- Get a copy of both replica sides, e.g. under /tmp/replica1 and /tmp/replica2 - Make sure dsync still crashes with them, e.g. doveadm -o mail=maildir:/tmp/replica1 sync maildir:/tmp/replica2 - Delete all mails and dovecot.index* files (but not dovecot.mailbox.log) - Make sure dsync still crashes - Send me the replicas - they should no longer contain anything sensitive As for fixing, you could see if deleting dovecot.mailbox.log from both replicas happens to fix this.
