Subject Gossip intermittently marks node as DOWN
Date Mon, 03 Mar 2014 14:16:25 GMT
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. 

 INFO [GossipTasks:1] 2014-02-28 07:51:10,937 Gossiper.java (line 863)

 Has anyone got any suggestions for fixing this? 
  
 Thanks 
 Phil
