I have a 3 node cluster, all nodes are master data enabled. this cluster is running from past 4 days and receiving data. Today when i noticed node stats , one node was particulay showing memory usage \> 95% while other nodes were around 50 to 60 %. Is this an memory leak.

Cluster details (elasticsearch is running in cluster)  
JDK 1.8.0.91  
ELasticsearch 2.3.1  
Docker version 17.05  
Verified there are no cirquit breakers, field data is limited under 12 k (limit is 830million), no queries are running.

Following is output of node stats
