---------------------------------------
Summary: 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
Attachments: 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.
