We had one of the node giving OOM java.lang.OutOfMemoryError: unable to create new native thread and then being unresponsive.

We tried to add the node back to the cluster but with no luck.

It doesn't seem to "Receive any notification "  messages from the other nodes.
Keeps "Sending notifications " in loop

Please see attached the logs of the node that is out of rotation.

Any inputs appreciated.

Thanks
