Service broker intermitent problems with remote db

I am having an intermitent problem with service broker where the intiator's sys.transmission queue will fill up with outbound messages. I've looked at the transmission queue message status and it is blank on the sender's db. I've profiled the target db and i'm getting a duplicate message error.

When i run select get_transmission_status('93C9FBF6-F951-DE11-9F2F-0022198CADC8') with the conversation handle i get the following message back,
A previously existing connection with the same peer was found after DNS lookup. This connection will be closed. All traffic will be redirected to the previously existing connection. This is an informational message only. No user action is required. State 116.
Now i would assume that it should be restarting the tcp connection between the 2 servers and then sending the ack messages back to the sender without problem but it never does. The only way i've found to fix the problem is to restart the sql server service on the sender's machine which closes and reopens the tcp connection and the messages will continue to process. Does anyone have any suggestions on what I should try to do to prevent this in the future?
