Elasticsearch 5.2.1 occupies more RAM space


(Rajeshkumar) #1

Hi,

I have installed ES 5.2.1 in my linus box RHEL 7.2. I have 32 Gb of RAM in my box. In my elasticsearch.yml I have set the property bootstrap.memory_lock: true and I have configured my heap sie as -Xms16g -Xmx16g.. I have 5 nodes in my cluster 1 tribe and 4 master/data node. Sometimes in any node the heap sie getting overflowed and the node is becoming unresponsive. When i check the RAM using the commandfree -h . It shows only 500MB is available.

let me know is there any other settings which I need to take care either in sever or in component level.

Hi

Could You count cache filesystem ??

You cannot exceed whatever you have defined as heap. If free shows very little memory then it's going to be the OS using it.
