Hi,

I've set up two openldap servers (ldap1.cpttm and ldap2.cpttm) for multi-master replication. It seems to work fine initially. However, later on it seems the replication has stopped: I can add new entries or change attribute values on ldap1.cpttm but ldap2.cpttm won't see the changes.

I confirmed that they are talking to each other with both tcpdump and syslog.

The configuration and the trace level log is attached below. Any idea to further troubleshoot this issue? Thanks in advance for any hint!

Both are running slapd 2.4.9-0ubuntu0.
