Subject High CPU load on one node in the cluster
Date Wed, 19 Feb 2014 08:30:05 GMT

I am running cassandra 2.0.3 cluster on 4 AWS nodes. memory arguments are
the following for each node :
-Xms8G -Xmx8G -Xmn800M

I am experiencing consistent high loads on one of the nodes. Each node is
getting approximately equal number of writes. I tried to have a look at the
logs and seems like CMS GC is running every 1-2 seconds.

Any pointers on how to debug this?
