>                 Key: PROTON-625
>                 URL: https://issues.apache.org/jira/browse/PROTON-625
>             Project: Qpid Proton
>          Issue Type: Bug
>          Components: proton-c
>    Affects Versions: 0.8
>            Reporter: michael goulish
>
> I am saving all my stuff so I can repro on demand.
> It doesn't happen every time, but it's about 50%.
> ------------------------------------------
> On one box, I have a dispatch router.
> On the other box, I have 10 clients: 5 Messenger-based receivers, and 5 qpid-messaging-based senders.
> Each client will handle 100 addresses, of the form "mick/0" ... "mick/1" ... & c.
> 100 messages will be sent to each address.
> I start the 5 receivers first.  They start OK.  Dispatch router happy & stable.
> Wait a few seconds.
> I start the 5 senders, from a bash script.
> The first sender is already sending when the 2nd, 3rd, 4th start.
> After a few of them start,but before all have finished starting,  a few seconds into the script, the crash occurs.  ( If they all start up successfully, no crash. )
> The crash occurs in the dispatch router.
