When trying to run cbench, i see the following exceptions on the controller:

2014-03-05 20:37:16.445 PST [nioEventLoopGroup-11-5] WARN i.n.channel.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
