dovecot - Jan 2014 - Is replication broken?

Hi,

Apologies for this being my 248th post about replication...

The current error I'm getting is:

Jan 30 12:10:54 Server1 dovecot: dsync-local(MailUser1): Error: dsync(
Server2.test.com): read() failed: read((fd)) failed: Connection reset by
peer

Subsequent errors are:

Jan 30 12:15:47 Server1 dovecot: dsync-local(MailUser1): Error: read(
Server2.test.com) failed: EOF

The above error is seen on Server1, after the initial sync completes of the
first mailbox (Sent folder to be precise).

Does anyone have an ideas as to what might be causing it?  These are brand
new rebuilds, running the latest build - I just can't seem to get this
working.

Bug maybe?



Configs are as follows:

Server1:

# 2.2.10: /usr/pkg/etc/dovecot/dovecot.conf
# OS: NetBSD 5.2 cobalt
auth_mechanisms = plain login
doveadm_password = secret

mail_plugins = " notify replication"
passdb {
  driver = passwd
}
plugin {
  mail_replica = tcp:Server2.test.com
}
protocols = imap
service aggregator {
  fifo_listener replication-notify-fifo {
    mode = 0666
  }
  unix_listener replication-notify {
    mode = 0600
  }
}
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  user = root
}
service imap-login {
  inet_listener imap {
    port = 0
  }
}

}

userdb {

this is a generic network error:
http://stackoverflow.com/questions/1434451/what-does-connection-reset-by-peer-mean

The other side of the communication channel closed the connection. It also 
does not neccessarily mean that other end point did it, but it could be a 
firewall, router, whatever in between as well.
