I'm currently doing load tests on a old JBoss AS 6.1.
But I have the problem that the EJB3 pool seems to be limited to 50.

In the JMX Console is see :

CreateCount 50  

CurrentSize 50  

RemoveCount 0  

MaxSize 50 

InvocationStatistics 
concurrentCalls='48' method name='applyRegulator' count='1902' minTime='108' maxTime='5825' totalTime='1874001' 

What's strange is that I can add the @Pool annotation or change the pool size in ejb3-interceptors-aop.xml but it still limits at 50.
