Hi,
I am using Elsticsearch5.5.3 with 4 node cluster( one node is just a coordinating node).
One of my node is showing 100% cpu usage always, and also i can see this below log message from elasticsearch.
[INFO ][o.e.m.j.JvmGcMonitorService] [node-1] [gc][5414000] overhead, spent [296ms] collecting in the last [1s]
16gb is the max and min memmory assigned for jvm now.
Can someone plesae help me to resolve this issue.
