[rules-users] Memory leak in 5.2/5.3

[vadlam]

we are seeing similar memory leak with 5.2.0.Cr1 version of drools.

are there any other alternatives such as using a different version of jbpm
jar if that is the cause of the problem?
we are currently using the jbpm-flow-5.1.0.Cr1.jar.

If not,

is there a method that removes all the facts from the ksession so that it
can be reused?

for ex, the existing code (simplified) is as follows:

ksession = knowledgeBase.newStatefulKnowledgeSession();

for (Object obj : objList)
        {
            ksession.insert(obj);
            
        }
 ksession.startProcess(ruleFlowProcessName);
        ksession.fireAllRules();
.... do some response processing here 


ksession.dispose();

Thomas,

Can you please elaborate on what you did to clean out the facts from the
memory ?
