> Key: DISPATCH-334
> URL: https://issues.apache.org/jira/browse/DISPATCH-334
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 0.6.0
> Reporter: Ted Ross
> Assignee: Ted Ross
> Priority: Blocker
> Fix For: 0.6.0
>
>
> Scenario:
> {noformat}
> +---------+ +---------+
> Sender1---->| | | |---->Receiver1
> | | | |
> | Router1 |========| Router2 |
> | | | |
> Sender2---->| | | |---->Receiver2
> +---------+ +---------+
> {noformat}
> All senders and receivers are using the same address, which is configured to
> be "balanced". When both Senders are operating, eventually one or both of
> the sending links will fail due to a sequence error:
> {noformat}
> ERROR:root:sequencing error, expected delivery-id 181, got 182
> {noformat}
> This occurs when one delivery results in a fanout of zero and is placed on
> the incoming link's undelivered list.
