>             Project: Qpid Dispatch
>          Issue Type: Bug
>    Affects Versions: 0.8.0
>            Reporter: Jakub Scholz
>            Assignee: Ganesh Murthy
>             Fix For: 1.0.0

> When I configure a multicast address in the Dispatch router, I expect that my 
> producer should be able to send the multicasts even when no receiver is 
> connected (i.e. the messages will be dropped). However, it seems that 
> Dispatch will not issue any credit to the producer unless there is some 
> receiver already connected and the producer is therefore stuck waiting for 
> the credit.
> Attached are the logs from both Dispatch as well as producer / receiver. I 
> attached also the router configuration file. It seems that the same problem 
> appears also after the receiver disconnects. The producer can still use the 
> remaining credit which was issued before, but the credit is not refreshed.
> This problem seems to be both with 0.8.0 as well as with the latest master.
