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:
We have a cluster with 7 nodes:
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.
