The python test qpid_tests.broker_0_9.echo.EchoTests.test_largest_single_frame_message for 0.9 AMQP protocol fails occasionally with the following stack trace:
The client and broker logs have records of the message being received by the client in timely manner (It took 3millisecond to deliver the message). However, the received message was not put into the client queue and test failed.
It is unclear at the moment whether it is an issue with threads or a bug in client code. More investigation is required.
The issue might cause sporadic timeouts in applications using 0.8...0.91 python API.
