------------------------------------
Assignee: Ken Giusti

> ---------------------------------------------------
>
> Key: DISPATCH-1336
> URL: https://issues.apache.org/jira/browse/DISPATCH-1336
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 1.7.0
> Environment: Fedora 29, Python 3
> Debug builds
> Proton git: branch master @ 0481a507c
> Dispatch git: branch master @ 7b3a8e25
> Reporter: Charles E. Rolke
> Assignee: Ken Giusti
> Priority: Major
>
> 1. A router is started with a simple
> qdrouterd
> 2. A single qpid-proton-c sender sends 100,000 messages to port 5672
> 3. A simple qpid-proton-c receiver receives the messages and accepts them.
> 4. In the sender's on_accept method occasionally the message IDs appear out of order.
> In this snippet the message id numbers are marching along in the correct order. Then settlements 77441..77459 jump ahead of settlement 77430. After that the streams get synchronized again and match for the remainder of the run.
> This is not necessarily wrong from an AMQP standpoint. But one might expect that the settlements would propagate from the receiver back to the sender in order every time.
> Can anyone explain how this happens?
