Sync replication halted



We are run a 3 node MMR with Openldap 2.4.39 on Ubuntu 14.04 (trusty)
Everything runs great with an occasional hiccup like this.  I see the
following in the logs that appear to be searches on the RID numbers that
are used for config replicationL


Nov 25 04:31:22 tn-ldap-a-2 slapd[5931]: syncprov_matchops: skipping
relayed sid 003
Nov 25 04:31:22 tn-ldap-a-2 slapd[5931]: syncprov_matchops: skipping
original sid 001
Nov 25 04:31:22 tn-ldap-a-2 slapd[5931]: syncprov_matchops: skipping
relayed sid 003
Nov 25 04:31:22 tn-ldap-a-2 slapd[5931]: syncprov_matchops: skipping
original sid 001

Imeadiately after this all changes show csn_too_old errors:

This happened on one node.  The third node had the same replication error
for a few miliseconds and then recovered.

I am attaching the database config file as well.
