title: ActiveMQ - Kahadb log files will not clear
body: <p>I've been tasked with investigating why the db-*.log files are not clearing.</p>
  
  <p>From what I have found through vast searching, everything points to the messages being on the queue still. I've looked at hawtio at the queues on all the configured topics and the queue size is zero.</p>
  
  <p>From my understanding the Enqueue size and Dequeue size in theory should be the same, but they're not. Seems my Dequeue size is 0.</p>
  
  <p>I've looked at the topics and there's no operation to purge them.</p>
  
  <p>I'd like to be able to clear out all messages so that the kahadb logs will disappear.</p>
