HI Am getting this error and seems like can it be resolved by increasing queue size. Is my assumption correct ? [2015-10-19 20:41:23,495][DEBUG][action.search.type] [Ghost Rider 2099] [logstash-2015.10.13][4], node[gdLxmHjmSiiHqWBb6hpZhA], [P], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@318396d] lastShard [true] org.elasticsearch.common.util.concurrent.EsRejectedExecutionException: rejected execution (queue capacity 1000) on org.elasticsearch.search.action.SearchServiceTransportAction$23@309f21ac Where can I find the config file so as to change the parameters. Looked into elasticsearch.yml but couldnt find any such setings ---

You can temporarily relieve this by changing threadpools, but you are overloading the node so it'll probably happen again. ---

Hi Whats the best way to overcome this problem ? Increasing nodes ? Is there a formula which tells me what is the best configuration to overcome this problem ---

There's no formula as it really depends on use case. How are you monitoring ES? ---

I tried using marvel but it was quiet resource intensive Also the indexer, is on a machine which is also running elasticsearch and kibana hence may be down on resources ---

What specs does the node have? ---

Its a Windows 2008 server with 4GB RAM. Though am trying to double the spec up but dont know if that would help to solve this problem ---

That's pretty small, adding more memory would help. ---
