The node is running on xxx.xxx.xxx.xxx. All of a sudden, it was not able to gossip and find the other nodes between data centres. We had two nodes indicated as down in DC1 but those two nodes were up and running in DC2. When we check the two nodes status in DC2, all the nodes in DC1 are denoted as DN and the other node in DC2 is denoted as down.
There seems to be a disconnect between the nodes. I have attached the thread dump of the node that was down.
