Hello! I am getting an errors: Caused by: org.elasticsearch.common.util.concurrent.EsRejectedExecutionException: rejected execution of org.elasticsearch.transport.TcpTransport$RequestHandler@670e2606 on EsThreadPoolExecutor[search, queue capacity = 1000, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@71540818[Running, pool size = 13, active threads = 13, queued tasks = 1000, completed tasks = 5097151]] Also i have a lot of "rejected" bulk and search operations in \_cat/thread\_pool?v: bulk 244 fetch\_shard\_started 0 fetch\_shard\_store 0 flush 0 force\_merge 0 generic 0 get 0 index 0 listener 0 management 0 refresh 0 search 11373 snapshot 0 warmer 0 We have a cluster with 7 nodes: 8 cpu 30 RAM Elasticsearch v5.1 I found that i can increase number of threadpool.search.queue\_size, but i think that i should increase the number of threads and pool size, but i am not really sure which number should be there. Probably i should increase something else. I am hoping for your support. Best regards. ---
