Anyone know how to debug cassandra processes just exiting?  There is no info in 
the cassandra logs and there is no heap dump file(which in the past has shown 
up in /opt/cassandra/bin directory for me).

This occurs when running a map/reduce job that put severe load on the system.  
The logs look completely fine.  I find it odd

 1.  No logs of why it exited at all
 2.  No heap dump which would imply there would be no logs as it crashed

Is there any other way a process can die and linux would log it somehow?  (like 
running out of memory)

Thanks,
Dean
