We have a hub and spoke architecture with connections from PHP clients using the PECL Stomp
(1.0.1) library.

On our hub I see the following:

On the spokes I'm seeing:

To the hub I'm sending to /topic/accounts with a header 'persistent' => 'true'.

To the spoke I am subscribing to /topic/accounts with a client-id of
'sutton_accounts'. I use the same 'sutton_accounts' value for the
'activemq.subscriptionName' header.

On the spoke my networkConnectors:
       <networkConnectors>
           <networkConnector uri="static://(ssl://the-hub:61617)"
               name="hub"
               duplex="true"
               conduitSubscriptions="false"
               dynamicOnly="false">
               <excludedDestinations>
                   <queue physicalName="software"/>
               </excludedDestinations>
               <staticallyIncludedDestinations>
                   <topic physicalName="accounts"/>
               </staticallyIncludedDestinations>
           </networkConnector>
       </networkConnectors>

I'm not certain I even know what the problem is let alone where it exists! Any assistance
in getting more info (which topic/queue is involved?) would be helpful!
