Thank for all the good suggestions. But my main question remains: Why is the max connection count set to 2? This cannot be the default, right?
Also, changing (default) parameters is very complicated in a CloudFoundry environment - I didn't get this working for other problems, e.g. with default thread pool size. Nevertheless, I first need to understand why TomEE uses 2 connections, then think about where to change that. -- Sent from: http://tomee-openejb.979440.n4.nabble.com/TomEE-Users-f979441.html
