> Key: AMQ-8023
> URL: https://issues.apache.org/jira/browse/AMQ-8023
> Project: ActiveMQ
> Issue Type: Bug
> Components: MQTT, Network of Brokers
> Affects Versions: 5.16.0
> Reporter: Gary Tully
> Assignee: Gary Tully
> Priority: Major
> Fix For: 5.17.0
>
>
> With MQTT clients using virtual topic subscriptions and clean session. In a
> network of brokers when the remove destination operations are bridged, it is
> possible for the re-subscribe to beat the removeDestination advisory and
> cause the remove to fail with an error, causing the bridge to fail. The
> advisories are in order, but are executed out of order on the remote network
> bridge, in error.
