Subject Re: Kernel keeps killing cassandra process - OOM
Date Sat, 22 Mar 2014 20:38:11 GMT
Is there anything else running on the boxes? Can you show us the output of
ps aux for the Cassandra process so we can see the -xmx, etc? JDK 7 may
help, even if you cannot upgrade Cassandra yet (which I would really
recommend since it moves items off-heap).
