Trying to get my new storage server synced up using dsync replication with
Followed the wiki and everything works great for the initial sync, for
about 4 hours, then I get some errors and it stops replicating:

dsync-local(user at host.com): Warning: Failed to do incremental sync for
mailbox INBOX, retry with a full sync
dsync-local(user at host.com): Error: Remote command returned error 75: ssh
-lusername <remote_ip> doveadm dsync-server -uuser at host.com -U

It happened around 2am. I restarted the new server dovecot process and it
started to copy back up again, and then happened about four hours later.  I
have about 10,000 accounts, and it chugs through the list to replicate
pretty well (~300Mbps), so I know it's working.  Just not sure why it's
failing after it's working so great.

Running 2.2.13 on both on FreeBSD.

Both show this:
# doveadm replicator status
Queued 'sync' requests
Queued 'high' requests
Queued 'low' requests
Queued 'failed' requests
Queued 'full resync' requests
Waiting 'failed' requests
Total number of known users   9957

Any ideas? Suggestions?
