Hi everyone, currently i'm facing an issue with my elasticsearch cluster. The version is very old which is ES 5.6.2, the logs is coming from Oracle SOA cluster which is collected using GELF and then into rabbitmq queue, and then processed by elasticsearch nodes, the dashboard is from graylog dashboard.
The error logs produced from es is
{"type":"es_rejected_execution_exception","reason":"rejected execution of org.elasticsearch.transport.TransportService$7@4778886f on EsThreadPoolExecutor[bulk, queue capacity = 200, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@2fa29bf8[Running, pool size = 16, active threads = 16, queued tasks = 200, completed tasks = 165]]"}
Has anyone experienced something like this?
Thanks!
