Service Broker Msg 33305
This may have been an existing problem with the database you backed up.  

Do you need to preserve the existing Service Broker conversations?  Messages?  Broker Identifier?

If you don't need the Service Broker messages, or to preserve any of its conversations or place in a distributed broker topology, you might end all the conversations WITH CLEANUP, or ALTER DATABASE ... SET NEW_BROKER.  

If you do need to fix this while preserving the other conversations and messages, you would probably need to open a support case, as there are really only a handful of people who can advise you on this.
