Ulf Lilleengen updated DISPATCH-387:
------------------------------------
Attachment: simple_direct.conf
Router config
> Router core dumps with misbehaving client
> -----------------------------------------
>
> Key: DISPATCH-387
> URL: https://issues.apache.org/jira/browse/DISPATCH-387
> Project: Qpid Dispatch
> Issue Type: Bug
> Reporter: Ulf Lilleengen
> Attachments: simple_direct.conf

>
> I have a simple setup with a router, a sender and a receiver.
> The receiver is qpid-receiver from qpid-cpp-client-devel. The sender is a
> modified version of https://github.com/orpiske/msg-perf-tool, and I've pushed
> my modifications that made the router crash here:
> https://github.com/lulf/msg-perf-tool/tree/lulf/dispatch-crash-sender
> The client might not behaving appropriately, so its entirely possible that I
> don't know what I'm doing! But I was thinking that the router should probably
> not crash due to misbehaving clients anyway.
