----------------------------------------
Summary: Connection Failure Race Conditions
Key: ARTEMIS-4476
URL: https://issues.apache.org/jira/browse/ARTEMIS-4476
Project: ActiveMQ Artemis
Issue Type: Task
Reporter: Clebert Suconic
Assignee: Clebert Suconic
Failure Detection has a possibility to a race condition with the processing of
the client packets (or frames in the case of AMQP).
This is because Netty detects the failure and removes the connection objects
while the packets are still processing things.
I was not able to reproduce this particular issue, but I have seen a case from
a memory dump where the consumer was created while the connection was already
dropped, leaving the consumer isolated without any communication with clients.
That particular case I could see a possibility because of these races.
I am adding tests to exercise connection failure in stress and I was able to
reproduce other issues.
