[389-users] Determining max CSN of running server

I'm having another replication problem where changes made on a particular server are not being replicated outward at all. Right now, I'm trying to determine what's going on during the replication process.

(Caveat: I'm still running an old version of 389ds: v1.3.10. In particular, the dsconf utility does not exist.)

My understanding is that when a server receives a change from a client, it wraps it up as a CSN and starts a replication session with its peers, during which it sends a message that states the greatest CSN that it originated. First off, is that a correct understanding?

If so, how can I determine what CSN a particular server is telling its replication peers during those sessions? I have a feeling that this server is, for some reason, sending an inaccurate number.

In the cn=replica,cn=...,cn=mapping tree,cn=config tree, there are entries for each of the servers topology peers, and they contain nsds50ruv attributes that seem to be the RUVs that that server has received from those peers, right? But the nsds50ruv attribute also exists directly in the cn=replica if you explicitly ask for it. Is it possible that this is the server's own RUV?

Can I rely on the nsds50ruv attributes on this server's peers' cn=replica nsds50ruv attribute values to be an accurate reflection of what this server is sending as its CSN in replication sessions?

Any other way to see what's going on in a replication session? (I'm even trying to decrypt a network capture, but I'm not having any luck with that yet.)

In particular, I see the max CSN for this server in all of these RUVs less than CSNs recorded in the server's own log files.
