      We can see it only SpecJMS2007 runs and it's intermittent. It does not cause any exceptions to be thrown at clients and server can recover from it. Continues as expected. We can only see that once this happens then SpecJMS2007 with given load does not success in sense that server did not handle given load. No other impact was seen.

      Based on discussion in [1] this is Netty issue which can be resolved by upgrade to newer version.
