[jira] [Commented] (QPID-7588) [Python Client 0-8..0-91] The
received message ocasionally might not be dispatched into the application
queue in timely manner
[ https://issues.apache.org/jira/browse/QPID-7588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15773210#comment-15773210 ]
Keith Wall commented on QPID-7588:
----------------------------------
This is probably just an environmental issue. The Apache CI hosts can be very slow. We'll factor out the timeout so the noise can be reduced.

> 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:
> {noformat}
> qpid_tests.broker_0_9.echo.EchoTests.test_largest_single_frame_message (from (TEST-python_pre1.0.xml))
> Failing for the past 1 build (Since Failed#1256 )
> Took 14 sec.

> 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.
