I've seen this on one of the QE machines.  The Broker.connect() is called on demand so 
something on the pulp server is constantly creating and destroying a gofer message 
consumer or producer.  Something strange though.  This message is only printed when a 
connection is created the first time.  The created connection is cached and reused across 
all sessions, so we should only see this message once for the life of the processing 
(interpreter) running the pulp application in wsgi.  So, it's unclear whether this is 
something bad happening in wsgi whereby the pulp application processing is dying and being 
re-spawned.  Or, this is part of the cause.  fwiw, the reconnect logic is handled in 
python-qpid so this isn't an auto-reconnect gone crazy thing.. I don't think.  A stack 
trace would really help.
