PROTON-2112: prevent fd overflow recovery during proactror shutdown
> segfault in epoll proactor shudown
> ----------------------------------
>
> Key: PROTON-2112
> URL: https://issues.apache.org/jira/browse/PROTON-2112
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.29.0
> Environment: Linux
> Reporter: Clifford Jansen
> Assignee: Clifford Jansen
> Priority: Major
> Attachments: bt.txt

> If an epoll proactor is dealing with file descriptor resource starvation at
> the time of shutdown, it can try to initiate new IO in conflict with other
> shutting down activity. Specifically, when freeing a connection's socket, it
> tries to resume any pause listeners.
> I suspect there is a missing check somewhere to see if
> proactor->shutting_down is set before attempting the resume. But it may
> require a more thorough dismantling of the overflow listener list before
> commencing to tear down straggling connections.
