Recently we rolled out new Search functionality to Production and from the same day we started seeing Elasticsearch 5.3.0 going down every other day.  
I allocated 30GB for JVM heap and we are running elasticsearch on Solid state disc.  
We are using Elasticsearch from 4 years and haven't seen this exception. any idea why and how to resolve this issue ?
