You might try monitoring the value in the corresponding mbean named something like jboss.remoting:host=,port=3873,service=invoker,transport= socket. That mbean tracks the thread pools.

It does involve some code writing - I created a class that extends AbstractJavaSamplerClient and used it within a Java Request Sampler within the JMeter script. This works well with stateless and stateful beans (don't use the JUnit Test Sampler for stateful beans).

Thanks Peter. We found the problem. It is the database(postgres). It's connections are limited to 50 and jboss sends to many queries to it when we perform stress tests. 
Thanks again.
