Stateful Session Bean memory leak in AS 7.1.1 (win 7, redhat linux)

created by Hans-Dieter Mader in JBoss AS 7 Development - View the full discussion



I have got a SFSB running on 7.1.1 standalone.

The SFSB has been migrated from ejb2 to ejb3.1 (Home, Remote, Bean impl., ejb-jar.xml).

Passivation on server is NoPassivate (simple).

The client calls come from a tomcat 7.


After running a time with a number of remote calls, the AS 7 vm is out of memory.

Force GC does not free the jvm memory pool "tenured gen" on windows or "ps old gen" on linux!

Only when I disable the Bean, the memory is freed.




                Properties jndiProps = new Properties();
                jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
                jndiProps.put("jboss.naming.client.ejb.context", true);
                jndiProps.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

                jndiProps.put(Context.SECURITY_PRINCIPAL, "username");
                jndiProps.put(Context.SECURITY_CREDENTIALS, "password");


                InitialContext context=new InitialContext( jndiProps );


               PortalHome pHome = (PortalHome)c.lookup("ejb:/PortalBean/PortalBean!uiportal.ejb.session.PortalHome?stateful");

               Portal pRemote = pHome.create();



               pRemote.ejbRemove(); // Bean Method annotaded with @Remove, also in Remote Interface -> the @PreDestroy method will be called by the server!!!!




Any idea is highliy appreciated!!!!
