Wouter, Yes it is possible that you have memory pressure. I'd probably:
1) Set bootstrap.mlockall: true in the elasticsearch.yml file 2) Once you're up and running (or when these GC pauses start to happen), check the node stats to see what you have in memory: curl "http://localhost:9200/_nodes/stats/jvm?pretty" That will give you a rough idea if you might need to bump that ES_HEAP_SIZE up some more (up to 1/2 of your available RAM or 30GB whichever is smaller). 3) If you're reaching the limits of RAM on a single node, then it might be time to add more nodes to distribute those shards out horizontally. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
