I've seen a very similar issue (ContextCSNs being newer on my consumers), and I believe it was fixed in OpenLDAP (2.4.26). Do the “CSN too old, ignoring” error messages spam endlessly in your consumer logs?

As for your other questions. You only need a single accesslog, and the clocks on your consumer nodes do not need to be in synch with the Provider (in deltasync replication).

Other than original query , I have additional queries about delta replication.
If have more than one consumers, do I need to decalre seprate access
logs for each of the replica ?
If I want to use changelog insteadof acesslog, where can I find documentation ?
