> Key: DISPATCH-1579
> URL: https://issues.apache.org/jira/browse/DISPATCH-1579
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 1.10.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Blocker
> Fix For: 1.11.0
>
>
> Create a two hop router network. Attach a single receiver on one router.
> Create 10 senders on the other router. Each sender should sent a large
> number of (unsettled) messages at a given priority (IOW 10 senders, one
> sender sends priority 0 messages, another sends priority 1 messages, etc).
> If the messages are large enough to trigger Q3 eventually most (all?) of the
> senders will hang stuck waiting for either settlement or deliveries to be
> forwarded. There is no recovery.
> I will post a reproducer soon.
