Follow on question - While following up on a request to verify replication within our Solr farm, I discovered a state that is puzzling. For a number of Solr 6 cores I see the master and the core replicating to the master having the same doc count, indexVersion number, and LastUpdatedDate values, however the Gen value is off by one (Master ahead by one). Replication is not being triggered.
Any ideas on what would cause this state, and the meaning of the version being the same and the gen different?
