[jira] [Created] (PROTON-1328) Creating two senders to same address
hangs
Brian Bouterse created PROTON-1328:
--------------------------------------
Summary: Creating two senders to same address hangs
Key: PROTON-1328
URL: https://issues.apache.org/jira/browse/PROTON-1328
Project: Qpid Proton
Issue Type: Bug
Components: python-binding
Affects Versions: 0.14.0
Environment: Fedora 24 using packages from F24 repos
Reporter: Brian Bouterse
Do this with the Python bindings for Proton:
1. create a connection
2. create sender A to address 'simple_queue' in a on_timer_task callback
3. send a message using sender A
4. create a second sender B to address 'simple_queue' in a on_timer_task callback
5. When you return control from the on_timer_task the second time proton never calls on_sendable() again. Also you see the following output with PN_TRACE_FRM=1
