We have a 2 node Cassandra 2.0.5 cluster running on a couple of VMWare hosted virtual machines using Ubuntu 12.04 for testing. As you can see from the log entries below the gossip connection between the nodes regularly goes DOWN and UP. We saw on another post that increasing the phi_convict_threshold may help with this so we increased that to '12' but we still get the same problem.
