Re: [rules-users] StatefulKnowledgeSession construction executes sequentially (no multithread)

I solved the problem. I experienced some memory leak using StatefulKnowledgeSession and immediately I discovered this http://drools.46999.n3.nabble.com/rules-users-Memory-leak-in-5-2-5-3-td32... post . It's a bug in JBPM 5.1.0 in conjunction with drools 5.2. JBPM leaks some memory when creating new StatefulKnowledgeSessions. When memory reaches certain memory threshold, GC seems to execute trying to free some memory and all we know part of GC is single-threaded. Using Drools 5.2 you can avoid this problem if you do not use JBPM integration (BPMN2 resources). In order to test it in a proper scenario I put some code (cpu consuming) between creation and dispose ( double a = Math.sqrt(2828282)*Math.sqrt(2828282) with several bucles) Thank you very much for your help, -- View this message in context: http://drools.46999.n3.nabble.com/StatefulKnowledgeSession-construction-e...
