------------------------------------
Summary: Race condition when auto deleting an address
Key: ARTEMIS-1792
URL: https://issues.apache.org/jira/browse/ARTEMIS-1792
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.5.0
Reporter: Lionel Cons
It seems that there is a race condition when auto deleting an address (i.e. via
{{auto-delete-addresses=true}}), at least when using STOMP.
Here is the scenario:
- 2 consumers on the same topic
- they issue an {{UNSUBSCRIBE}} frame at the same time
Artemis returns a AMQ119203 error: Address Does Not Exist.
Here are logs.
consumer 1 subscribes:
{code}
# 2018/04/09-11:43:24 mbtf[1699.1]: => SUBSCRIBE frame
# 2018/04/09-11:43:24 mbtf[1699.1]: H ack:client
# 2018/04/09-11:43:24 mbtf[1699.1]: H destination:/topic/test.mbtf.o7zlADh7

# 2018/04/09-11:43:24 mbtf[1699.1]: H receipt:324b068-5acb35bc-6a3-32d-2
{code}
consumer 2 subscribes:
{code}
# 2018/04/09-11:43:24 mbtf[1699.2]: => SUBSCRIBE frame
# 2018/04/09-11:43:24 mbtf[1699.2]: H ack:client

{code}
receipts are received
producer (a third thread/connection) sends one message and disconnects
both consumers receive the message and acknowledge it
consumer 1 and 2 unsubscribe at the same time:
{code}
# 2018/04/09-11:43:29 mbtf[1699.2]: => UNSUBSCRIBE frame
# 2018/04/09-11:43:29 mbtf[1699.1]: => UNSUBSCRIBE frame
