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.
