Current ES prod has almost all primary shards allocated on a single server, which is strained much more so than all the others. After ES is upgraded, we should review the shard placement or do some manual intervention to force a more even distribution.
We updated the Java version and ES_HEAP settings on prod last week. Primary shard placement looks sane now and we get much more even load.
