It's possible that can happen as well. When this happens, usually

changes are

propagated to the consumer through the master anyway, since that

master is receiving

updates from the other master(s).

I wonder if it is because we had a network blip between sites and there was an update/lock at the time so when the network came back up and the master tried to send updates, there was already a stale lock? It's actually multi-master replication - there are two masters and it's one of the masters which did this.

Did the replication monitor documentation help at all?

The documentation on the repl-monitor script wasn't detailed enough perhaps? I tried getting this to work but couldn't. I tried every setting in the config file I could to no avail. It seems to be hard-coded to port 389 and I am running SSL (well, TLS).

In any case, I really need something like SNMP alerts when there are replication problems. I suppose I can look for the string "NSMMReplicationPlugin" in the error log ...
