Were using SolrCloud 4.10.3 with a 3 node solr cluster with 2 collections of 3 shards each.
Collection 1: approx size: 15.3 GB Collection 2: size: 1.2GB
Our heap size is 8GB and off heap is 15GB. We have a realtime feed into solr for one of our collections (the other is pretty static). We are constantly getting an out of memory error.
Can anyone help us as to the reason? Should be we having additional shards to spread the load? Or do we need to keep giving more off heap memory? All the cloudera heap graphs show that we are find for heap space (we rarely go above 6.5GB) and GC pauses are not an issue.
