How to diagnose es\_rejected\_execution\_exception? I see a number of threads about running out of threads (ha ha) but I didn't find one that answers the following question: I don't think there's that much going on on the system, so if there are 1,000 requests queued and more requests coming in that sounds wrong to me. **How do I find out what these requests are, so I can identify and fix whatever is causing them?** I have X-pack monitoring if that's any help, but I don't know what to look for. ---

Please? - there must be somebody who knows something about Elasticsearch performance? ---
