Subject Kernel keeps killing cassandra process - OOM
Date Sat, 22 Mar 2014 14:48:02 GMT
Hi,
I have a 3 node cassandra test cluster. The nodes have 4 GB total memory/2
cores. Cassndra run with all default settings.
But, the cassandra process keeps getting killed due to OOM. Cassandra
version in use is 1.1.9.
here are the settings in use:

compaction_throughput_mb_per_sec: 16

How do I resolve this?
