Stefano Ortolani created CASSANDRA-11723:
--------------------------------------------

             Summary: Cassandra upgrade from 2.1.11 to 3.0.5 leads to unstable 
nodes
                 Key: CASSANDRA-11723
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11723
             Project: Cassandra
          Issue Type: Bug
            Reporter: Stefano Ortolani
            Priority: Critical


Upgrade seems fine, but any restart of the node might lead to a situation where 
the node just dies after 30 seconds / 1 minute. 

Nothing in the logs besides many "FailureDetector.java:456 - Ignoring interval 
time of 3000892567 for /10.12.x.y" output every second (against all other 
nodes) in debug.log plus some spurious GraphiteErrors/ReadRepair notifications:

I know this is not much but nothing else gets to dmesg or to any other log. Any 
suggestion how to debug this further?

I upgraded two nodes so far, and it happened on both nodes.
