Some Dsync Replication Errors

[Asai]

Greetings,

Working on setting up replication and ran into some errors I have 
questions about and wondering if there's something I need to change.

This one is fairly common:

Sep  3 12:58:25 molecular dovecot: dsync-server(user at domain.org): 
Warning: Failed to do incremental sync for mailbox INBOX, retry with a 
full sync (Modseq 100298 no longer in transaction log)

These two I ran into yesterday and today:

Sep  2 11:13:32 molecular dovecot: dsync-server(user2 at domain2.org): 
Error: Timeout during state=slave_recv_last_common

Sep  3 12:52:08 molecular dovecot: dsync-server(user3 at domain3.org): 
Error: read(remote.mailserver.net) failed: EOF


Configs:

mail_plugins = notify replication

service doveadm {

         inet_listener {

                 port = 1234

         }

}

service replicator {

         process_min_avail = 1

         unix_listener replicator-doveadm {

                 mode = 0600

         }

}

service aggregator {

     fifo_listener replication-notify-fifo {

         user = vmail

         mode = 0600

     }

     unix_listener replication-notify {

         user = vmail

         mode = 0600

     }

}

plugin {

         mail_replica = tcp:sub.domain.org:1234

}


And doveconf -n:
