Subject cassandra just heap dump, no log info
Date Wed, 18 Sep 2013 12:21:05 GMT
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)
