ActiveMQ wasn't my decision and it's not easily changeable (politically). It's hard to believe that no one would have run across this if it was a widespread problem given how many people are using ActiveMQ with JBoss. I'm guessing it's something with my configuration. Or... Let me ask this a different way: Does the CachedConnectionManager assume that a JMS connection created inside a method should always be closed when that method returns? It's working fine with the CachedConnectionManager auto-close turned off so I don't think there's a fundamental problem with how I'm using JMS. I'm not seeing zombie JMS connections on the server.
