title: Rabbitmq unroutable messages published to the default exchange?
body: <p>I have just learned I have a high number of unroutable messages being published to the default exchange.</p>
  <p>Because this is the default exchange, I am having a hard time tracking down the source of these unroutable messages. If this was not the default exchange I could find the publishing client by searching my code base by exchange name.  Additionally, I can't effectively bind to the default exchange because I do not know the routing keys of the messages being published.</p>
  <p>Is there any way I can find these messages without starting/stopping all my clients one at a time?</p>
