Description of problem:

15:40:27,367 INFO  [org.rhq.server.metrics.StorageSession] (Cassandra Java Driver worker-12) /17.176.208.118 is up
15:40:27,367 INFO  [org.rhq.server.metrics.StorageSession] (Cassandra Java Driver worker-12) Changing request throughput from 30000.0 request/sec to 40000.0 requests/sec

15:40:28,096 INFO  [org.rhq.server.metrics.StorageSession] (Cassandra Java Driver worker-13) Changing request throughput from 40000.0 request/sec to 50000.0 requests/sec
15:40:28,096 INFO  [org.rhq.enterprise.server.storage.StorageClusterMonitor] (Cassandra Java Driver worker-13) Storage node at 17.176.208.118 is up

Seems like a race condition... The rate should be 30000 not go up to 50000

I am marking this as a blocker for bug 1100309 which is the BZ against which the throttling work is being tracked.
