ElasticSearch hung


(Chinmoy Das) #1

We are using ElasticSearch(2.1.1) , with Logstash 2.1.1 and Kibana 4.3.1 in a production environment of a national payment switch in India. Unfortunately after running smoothly for 6 months, ElasticSearch started hanging a few times and coming up automatically within 15 minutes. The total size of all index files is around 1.2 GB. The error is as below. Any solution is welcome.
