Our Elasticsearch service is intermittently crashing. It is in a docker container which is automatically restarted. On restart, we see a ton of errors like this:
RemoteTransportException[[medtasker][172.19.0.11:9300][indices:data/read/search[phase/query]]]; nested: EsRejectedExecution
Exception[rejected execution of org.elasticsearch.transport.TransportService$4@224550fc on EsThreadPoolExecutor[search, que
ue capacity = 1000, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@7bdc0fd7[Running, pool size = 7, active t
hreads = 7, queued tasks = 1000, completed tasks = 100438789]]];
What does it mean?
