A couple of things:

You don't use a networkConnector for master/slave.  This is definitely 
causing a problem.  Network Connectors are to connect to *other* 
master/slave pairs to provide scaling of traffic load.   Remember: 
Master/Slave *only* provides high availability for the messages in a 
single data store.

     Action 1: Remove <networkConnector /> config from both configs.

Your <destinationPolicy/> configuration is rather limiting.  The 
configuration of memoryLimit = 1mb means that each destination only gets 
1 Mb of memory.  This is a good default setting, but when you have a 
busy destination, be sure to add an entry for the busy destination to 
give it more than 1mb, or increase the default.

     Action 2: After fixing and testing #1, look to tweak the default 
memoryLimit, or add per-destination configs for busy queues/topics.

Hope this helps!
