title: Multiple Cassandra node goes down
body: <p>WE have a 12 node cassandra cluster across 2 different datacenter. We are migrating the data from sql DB to cassandra through a net application and there is another .net app thats reads data from the cassandra. Off recently we are seeing one or the other node going down (nodetool status shows DN and the service is stopped on it). Below is the output of the nodetool status. WE have to start the service to again get it working but it stops again.</p>
