Did you read and apply the Stuck Messages section of the page you linked? Also, is your F5 configured to make clients sticky to a particular broker? ActiveMQ is not like a web server where each request is stateless; you can't bounce a connected client between brokers and have it behave correctly. There are URI options that will let your clients automatically do their own load balancing, if you find you don't trust what the F5 is doing. See the randomize URI option on http://activemq.apache.org/failover-transport-reference.html.
I'm not sure what happens if your network transport connects to yourself. You might try taking the current host out of the networkConnector in each host's config. Finally, I assume the F5 isn't doing load balancing on the connections between the between...
