Hi All,
We have cluster of 3 nodes with 64GB RAM each. My cluster was running in
healthy state. Suddenly one machine's cassandra daemon stops working and
shut down.
On restarting it after 2 minutes it again stops and is getting stop after
returning below error in cassandra.log
Java HotSpot(TM) 64-Bit Server VM warning: INFO:

This is our production cluster and rest 2 nodes are still in healthy state.
We have also changed heap size from 10G to 20 G but problem still persists.
Please help in finding the reason behind this.
