             Summary: HA add UUID tag to avoid using an out of date queue.
                 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


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.
