      I have a node that has been joining for around 24 hours. My application is configured with the IP address of the joining node in the list of nodes to connect to (ruby driver), and I have been getting around 200 events of this NPE per hour. I removed the IP of the joining node from the list of nodes for my app to connect to and the errors stopped.
