> URL: https://issues.apache.org/jira/browse/AMQ-4897
> Project: ActiveMQ
> Issue Type: Bug

>
> There's a small chance of the race condition when using priority backup with
> extremely small reconnect delay (0). In that case, the failover transport
> will get into inconsistent state. The client will stay connected to the
> "non-priority" broker, but the priority backup will not be created due to
> this inconsistency.
> The solution is to synchronise handling of connection failure with the
> reconnect mutex.
