Hi all Recently we start to face error: EsRejectedExecutionException[rejected execution (queue capacity 1000) The strange thing that there is no parallel or hard requests. After some actions node start to throw that kind of error for any request, even for one shard with size set to 0 (aggregation type of request). We tried to enable slowlog, but that wasn't very helpful - there simply log of queries before breakdown. There shouldn't be any other background process, so there literally only 1 request, that throw error of query capacity. So the question is - how can i understand the reason of problem? Maybe there is a way to see currently running process? Will be grateful for any suggestions. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I'm also facing the same issue. I have copied 20 index from an elasticsearch instance to a new instance. After that when I started firing search queries in the new instance from my code, after 20-30 calls I'm getting error: {[aRGdCWK2QsyfvgGJLt6xrA][quanteye\_ing][1]: EsRejectedExecutionException[rejected execution (queue capacity 1000) on org.elasticsearch.search.action.SearchServiceTransportAction$23@29fdcd0e]} With the same amount of data and same calling code the old instance was running fine.. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Is this version 1.4.4? Can you create a thread dump with tools like jstack? If many threads are in the state BLOCKING, this would be interesting.
