[jira] [Closed] (QPID-8347) Receive() blocks forever once timeout

> Key: QPID-8347
> URL: https://issues.apache.org/jira/browse/QPID-8347
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Affects Versions: qpid-cpp-1.39.0
> Environment: OS: Ubuntu Bionic
> QPID C++ version 1.39.0
> QPID Proton version 0.28.0
> RabbitMQ Broker version 3.6.10

> RabbimtMQ AMQP 1.0 plugin Version 3.6.10

> Priority: Blocker

> Hello All,
> I am trying to use QPID C++ messaging API with a RabbitMQ Broker communicating over AMQP 1.0 protocol. When the receive() call times out, the RabbitMQ Broker throws an error and closes the session. The QPID C++ client then hangs indefinitely in the receive call. I believe that this is a bug in the QPID C++ API because it should always respect the client provided timeout, no mater what the Broker does. I also wrote a bug for RabbitMQ AMQP 1.0 plugin: [https://github.com/rabbitmq/rabbitmq-amqp1.0/issues/90]
>
> Update: After further testing, it seems like Qpid Proton handles the timeout case correctly with RabbitMQ Broker, isolating this issue to the C++ API.
