             Summary: Better handle critical thread exits
                 Key: CASSANDRA-8114
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8114
             Project: Cassandra
          Issue Type: Improvement
            Reporter: sankalp kohli
            Priority: Minor


We have seen on 2 occasion where a critical thread exited due to some exception 
and C* was still running. I see two options to detect such thread deaths
1) Write a wrapper around such Runnable which takes some action if the thread 
is about to exit.
2) Write something in uncaught exception handler which identifies a thread by 
name and alerts if it is a critical thread. 

Once we can better detect such things, we can configure action on it like 
alerting or killing C*.
