> Environment: Fedora 29, python 3.7.3
> Fedora 28, python 2.7.15
> Reporter: Chuck Rolke
> Assignee: Chuck Rolke
> Priority: Major
> Fix For: proton-c-0.28.0
>
> Attachments: PROTON-2039.patch

>
> To demonstrate: execute python/examples/helloworld_direct.py two times within a few seconds. The first time works and the second time fails with an 'Address already in use' error.
> The expectation is that this program can be run many times in quick succession.
