------------------------------------
    Component/s: STOMP

> 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
>          Components: STOMP
>    Affects Versions: 2.5.0
>            Reporter: Lionel Cons
>            Priority: Major
>
> 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
