ES\_HEAP\_SIZE ES\_MAX\_MEM ES\_MIN\_MEM are environment variables. They need to be specified on the command line. For example: ES\_HEAP\_SIZE=4g bin/elasticsearch -f To get JVM stats, you need to set jvm=true on stats request: curl -XGET '[http://localhost:9200/\_cluster/nodes/stats?jvm=true&pretty=true](http://localhost:9200/_cluster/nodes/stats?jvm=true&pretty=true)' To understand how much memory you need, give it as much as you can, put some load and monitor "jvm.mem.heap\_used" in the output of the stats command above. If this number ever goes and stays above 90% of available heap it's typically a good indicator that you need more. There is a small Russian elasticsearch forum - [https://groups.google.com/forum/?fromgroups=#!forum/elasticsearch-ru](https://groups.google.com/forum/?fromgroups=#!forum/elasticsearch-ru) On Saturday, February 9, 2013 12:57:04 PM UTC-5, Николай Измайлов wrote: > In continuation of the topic > [Constantly falls elasticsearch · Issue #2636 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/2636#issuecomment-13332877) > > in continuation of the topic > [Constantly falls elasticsearch · Issue #2636 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/2636#issuecomment-13332877) > On the page > [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/setup/installation.html) it > is said that it is necessary to increase ES\_HEAP\_SIZE ES\_MAX\_MEM > ES\_MIN\_MEM, but I have not found this configuration then > /etc/elasticsearch/elasticsearch.yml.

Hello there, We are having the same exact problem with a really resource hungry query: 5 nodes with 16GB ES\_HEAP\_SIZE 1.2 Billion records inside 1 index with 5 shards Whenever we start running an aggregate query the whole cluster breaks and disconnects. Why can't it just not return results and simple give and error without actually killing the entire cluster? Cheers!
