--------------------------------------
Assignee: Ganesh Murthy
> Getting connections via the router management protocol causes AMQP framing
> errors
> ---------------------------------------------------------------------------------
>
> Key: DISPATCH-974
> URL: https://issues.apache.org/jira/browse/DISPATCH-974
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Management Agent
> Affects Versions: 1.0.1
> Reporter: Marcel Meulemans
> Assignee: Ganesh Murthy
> Priority: Major
> Attachments: qdrouter-frame-errors.pcapng.gz
>
>
> I am running a standalone router with 5000 clients connected. When I try to
> get all connections via qdstat (qdstat --limit 5000 -c) something goes wrong
> (seems to be a framing error). The output from qdstat is:
> {{ MessageException: [-10]: data error: (null)}}
> The problems seems to somehow be related to result size because when I set
> the limit to less I get the list of connections as expected. In my situation
> the critical limit is 3447 (i.e. 3447 result in the expected list of
> connections, 3448 result in the error above). It does not seem to be frame
> size related because getting 3447 connection is already spread over transfer
> frames (256182, 256512 and 159399 bytes).
> The error is not qdstat related because using some plain proton code to
> create a management query results in the same problem. Ultimately the call to
> pn_message_decode with data receive from the router fails (also wireshark can
> not decode the final frame).
> I have attached a wireshark dump to the qdstat session with the router
> ([^qdrouter-frame-errors.pcapng.gz]). The logs of the router (at info level)
> contain no further information.
