So, ideally only one instance should be up and running at a time. That's true we only see one instance serving requests but we do see some activity in CPU for the standby solr instance. These instances are writing to shared disk. My question is, why do we see activity is standby solr even if it is not serving any requests. Is there any replication of in-memory indexes between these instances? Any pointers to this are welcome. Regards, Prateek Jain
