QUESTION:: Is the session maintaining references to those objects ever after 
executing them? Why are the objects not being released? 

Specially I'd imagine for a STATELESS session (which is what I've set as 
default).

Using JMeter this system crashes every time under load, even with a single 
Thread. Clearly objects are not being released.

The error I get may help you: (Along with out of memory). This exception only 
comes under Load conditions.
Admin:ERROR: [com.myserver.brms.demos.certify.web.servlet.CertifyWebRequests]

Please help me! This is the only downtime issue I face and unfortunatley its 
the most critical point of failure.
    

Ok, I think I figured it out. But please confirm.

The Rule Engine Session DOES NOT release objects. (But hten why have a 
Stateless session?) if the duration of use of the session is not going to be 
long?

The solution: Pool the RuleBase and on a request createa freesh session from it 
each time a request comes in!

Let me know if the cocept is sound or what I'm thinking is now correct.

Thanks,
Arjun
