Subject Background flushing appears to peg CPU
Date Thu, 27 Feb 2014 07:46:57 GMT

Using Cassandra 2.0.5 we seem to be running into an issue with a
continuous flush of a column family that has no current data ingress.
After disconnecting all clients from the node, the Cassandra instance
seems to continuously flushing a specific column family with this line
appearing all over the logs:

INFO [OptionalTasks:1] 2014-02-27 07:36:39,366
(line 63) - flushing high-traffic column family CFS(Keyspace='bar',
ColumnFamily='foo') (estimated 70078271 bytes)

Restarting the node didn't appear to change the situation.

Does anybody know why this might be happening for a column family that
appears not to be receiving any writes?
