Comment 8 for bug 1599104

Not a bad workaround, but you have be extra cautious not to delete the queues having unprocessed messages. You will have to make sure the heat-api is not taking any requests, and that all the existing messages in queue are processed. IMO, this needs to be fixed properly so that the queues are auto-deleted when the underlying connections are gone/reset. I am not sure how part of it though.
