Hi,

I am facing issue of elasticsearch leaking memory beyond what is heap memory given... for e.g I have server with 32GB memory and heap memory given is 20GB. But after some time It goes beyong 20GB and server reaches to 96% memory usage. So please help me.

Elasticsearch uses what you assign to heap, anything else is the OS caching files that Elasticsearch is using.

When I troubleshooted it shows me In resource monitor It shows huge difference between Commited memory (i.e near to what i have given 20gb) and Working set memory it is showing around 30GB. And Its not on other node.... So please suggest me what can i do here ??
