             Summary: Cassandra hangs while reading saved cache
                 Key: CASSANDRA-5986
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5986
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: cuser
             Fix For: 2.0


We've got a cluster ~6Tb size running on 5 nodes with vnodes(256) enabled.

After some cache heat-up one of the nodes was restarted and cassandra just hangs with no error. Last message:

All other nodes are restarting successfuly.
