      Description

      Hawtio is causing a high load on the server within the activemq tab. This occurs with a moderate load (approximately queues).

      At present the initial triage of this issue suggests it is isolated to the core HawtIO component and as a result it is being tracked in our Fuse project with component HawtIO. The use of AMQ is simply around the test case at present.

      The goal of this JIRA is exploratory in that we need to understand the behavior, how this use case fits into the current design of HawtIO and what we can do about it.
