> Multicast sender with no receiver has first 250 messages released
> -----------------------------------------------------------------
>
>                 Key: DISPATCH-1423
>                 URL: https://issues.apache.org/jira/browse/DISPATCH-1423
>             Project: Qpid Dispatch
>          Issue Type: Bug
>          Components: Routing Engine
>    Affects Versions: 1.8.0
>            Reporter: Charles E. Rolke
>            Assignee: Ken Giusti
>            Priority: Major
>         Attachments: INTB-250-released-1.8.0.html, INTB.conf
>
>
> When a sender starts and there's no receiver already attached then the first 
> 250 messages the sender sends get released. After that the router waits for 
> the a receiver to attach before issuing more credit to the sender. The proton 
> c++ simple_send and simple receive clients expose this problem.
> 1. Start router with attached config file
> 2. Start sender
>     simple_send -a 127.0.0.1:5672/multicast/q1 -m 500
> 3. Start receiver
>    simple_recv -a 127.0.0.1:5672/multicast/q1 -m 500
> The sender competes with 'all messages confirmed'.
> The receiver is waiting for the second 250 messages.
