> Key: QPID-4428
> URL: https://issues.apache.org/jira/browse/QPID-4428
> Project: Qpid
> Issue Type: Bug
> Components: C++ Clustering
> Affects Versions: 0.19
> Reporter: Alan Conway
> Assignee: Alan Conway
> Fix For: 0.19
>
>
> Here's the scenario: we have a cluster with primary A and backups B and C.
> There is a queue Q that is replicated to both. Now A dies and B takes over as
> primary. Before C has connected to B, a client destroys Q and creates a new
> queue with the same name, Q. When C does connect it sees a queue named Q and
> mistakenly assumes it is the same queue as it's own Q - so it has an
> incorrect replica of Q. The same scenario applies to exchanges.
> The fix is to tag queues and exchanges with a UUID, so backups can identify
> that the queue has changed even if the name is the same.
