>          Issue Type: Bug
>          Components: Router Node

>            Assignee: Ganesh Murthy
>            Priority: Major
>             Fix For: 1.5.0
>         Attachments: test.patch
> Ran the following scenario on an edge router:
> 1 sender (not presettled)
> 3 receivers
> multicast
> large message
> If I have one of the receivers close its connection while in the middle of a multi frame
transfer the router marks the message as "discard" and does not forward the remaining frames
to the two remaining clients, thus stalling their links.
