---------------------------------------
Assignee: Ganesh Murthy
> Intermittent router hang while running QIT's AMQP large content test
> --------------------------------------------------------------------
>
> Key: DISPATCH-1110
> URL: https://issues.apache.org/jira/browse/DISPATCH-1110
> Project: Qpid Dispatch
> Issue Type: Bug
> Environment: Standard QIT environment.
> Once QIT is built and installed, the environment is set using the config.sh
> file. See QUICKSTART for details.
> Reporter: Kim van der Riet
> Assignee: Ganesh Murthy
> Priority: Major
> Attachments: qdrouterd.conf

> When running the Qpid Interop Test's AMQP large content test, a stand-alone
> router will intermittently hang and cause the test to time out.
> The failure appears to be limited to either the AMQP list or map types, and
> usually with the C++ client as the message sender. The C++, Python2 and
> Python3 as receiver clients have all seen this failure, but the Python2
> receiver client seems to reproduce more readily on my hardware.
> In all cases, the test fails when the router sends what I suppose is the
> final transfer of a large message (I have not added up/counted the bytes of
> the many preceding transfers) to the consumer. The consumer then sends a
> disposition, but the router does not respond again until the test times out.
> The consumer can be seen to send heartbeats to the router, but the router
> does not send any of its own.
