SyncREPL generates high traffic to calculate delta
I have the following configuration, in OpenLDAP 2.3.32 (i know i have to
upgrade to 2.3.38):
Master -> Pivot -> Slave on 3 different servers. SyncRepl replicates in
RefreshOnly mode, a sub-tree.
When i dump the TLS traffic during a replication of a add or delete
operation, i have around 6000 TCP packets between Master and Pivot, and
only 40 packets between Pivot and Slave. My sub-tree contains 5500
entries. So, i concluded that Pivot SyncRepl ask the entire sub-tree.
Is it a known problem ? Does it come from the configuration ?
Another topic about syncrepl : When the Pivot is stopped longer than the
interval setting, and restarted, i need to restart the Slave because it
doesn't retry connection on the Pivot ? And also, it doesn't use the
slapd logs the following error:

Is it a known problem ?
