Attachment: p2239.diff
> epoll proactor race condition on connection teardown with heartbeats
> --------------------------------------------------------------------
>
> Key: PROTON-2239
> URL: https://issues.apache.org/jira/browse/PROTON-2239
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.28.0
> Reporter: Clifford Jansen
> Assignee: Clifford Jansen
> Priority: Major
> Attachments: p2239.diff, xxx.c
>
>
> If a connection with heartbeats is closed at about the same time to when its
> idle timeout timer fires, it is possible to have two threads believing they
> are the last activity on the connection. Both threads proceed to free the
> same resources leading to memory corruption and various crashes.
> The existing code has guards for this exact situation, but there is an
> Achilles heel somewhere.
