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 command
free -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.
