</div><div>I do not think it comes from drools. I did project with 200k rules, it is slow to build the package but once this is done, the rest works perfectly.<br>Have you tried to cut your drl file in smaller files ?<br>

Hi Nicolas
<br><br>Thx for your quick answer.
<br><br>Ok, i forgot some informations:
<br>Using : Java6.0.45 X64 (same problems using Java 7 X64)
<br><br>No, i don't use listeners.
<br>I tried with up to 10Gig without success.
<br><br>My (reduced) workflow is :
<br><br>1) <code><br>kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
<br>kbuilder.add(ResourceFactory.newClassPathResource(RULES_PATH, getClass()), ResourceType.DRL);
<br>kbase = KnowledgeBaseFactory.newKnowledgeBase();
<br>kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
<br></code><br>2) <code><br>StatefulKnowledgeSession ruleSession = kbase.newStatefulKnowledgeSession();
<br></code> so far so good
<br>3) insert two supporter objects in session
<br>4) add two more worker objects in session
<br>5) fire all rules
<br>6) read and retract all expected objects
<br>7) dispose session
<br><br>Processing Steps 2)-7) (in a loop with different worker objects, to produce load, so there is always only
<br> one session active) work fine for a view times (3-9) then the mentioned exception occurs.
<br>I also tried it with 10gig for the jvm but in either test the memoryload does not exceed 3gig.
<br><br>With a reduced rules file size (to < 500k; removed some rules, to test this) i can handle 300000(!)
<br>loops without any exceptions.
<br><br>Hope this infos will help.
<br><br>Regards
<br>Peter
