----------------------------------

             Summary: Cassandra 2.0.1 OutOfMemoryError:  Requested array size exceeds VM limit
                 Key: CASSANDRA-6260
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6260
             Project: Cassandra
          Issue Type: Bug
         Environment: Cassandra server 2.0.1
            Reporter: Prateek
            Priority: Critical


I am running cassandra 2.0.1 server with cascading client https://github.com/ifesdjeen/cascading-cassandra/ (v 1.0.0-rc6). I am running a problem on restarting one of the nodes in the cassandra cluster. All other nodes in the cluster started properly without any issues. I had originally assigned 8G of RAM to heap space. I tried starting the node with 12G of RAM but it still fails with the following error. This is currently blocking a production release so appreciate your quick response.
