"Re: KnowledgeBase keeps links to stateful sessions after disposing" To view the discussion, visit: http://community.jboss.org/message/640299#640299 -------------------------------------------------------------- Hi, Tihomir, thank you for reply. I am observing memory leak with stateless sessions too. Here is simple code below: public static void main(String... args) { KnowledgeBase base = KnowledgeBaseFactory.newKnowledgeBase(); waitForKeyPress(); for (int i = 0; i (); for (int i = 0; i < 1000; i++) { list.add(new Date()); } return list; } private static void waitForKeyPress() { try { System.in.read(new byte[2]); } catch (IOException e) { e.printStackTrace(); } } Here we simply create 500 stateless sessions and insert in each "heavy" object (list of 1000 dates). Below is jConsole screenshot made while programm waiting for second key press: http://community.jboss.org/servlet/JiveServlet/showImage/2-640299-17450/Memory.png http://community.jboss.org/servlet/JiveServlet/downloadImage/2-640299-17450/450-371/Memory.png As you can see java process consumes ~3Mb before and 22Mb after invoiking sessions. Below is a screenshot of my debugger, that was made after invoiking sessions: http://community.jboss.org/servlet/JiveServlet/showImage/2-640299-17451/Debug.png http://community.jboss.org/servlet/JiveServlet/downloadImage/2-640299-17451/450-415/Debug.png You can see that knowledge base keeps 500 references to ProcessRuntime objects. The picture is the same when we using statefull sessions and dispose them by dispose() method. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/640299#640299] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
