Each zip contains source files as well as deployables: opensocket-jbm-queue-service.xml This is the definition of a JBoss Messaging queue. Please deploy this first FastInfosetWebProject.war Please excuse the name here, have double used this project. Ignore the class FastInfosetServlet as this is not used. In this case, there is a servlet called OpenSocketServlet that I'm using as a client. When that servlet is invoked, it sends 1,000 messages to the JMS queue listed above and then returns to the browser that it has done this. OpenSocketEjbProject.jar This is the MDB that gets the JMS messages sent above, then it calls back to a WS in the FastInfosetWebProject.war for each JMS message that it gets. The web service (in the war above) will print out to stdout every time it receives 200 more messages (just so you can see that things are happening). To reproduce: 1.) Deploy the queue XML file, then the WAR file, then the EJB JAR file. 2.) Hit this URL in a browswer: http://localhost:8080/FastInfosetWebProject/OpenSocketServlet?name=World 3.) Right away, go ahead an hit that same URL again 4.) Open a terminal window and run this command: ""netstat -an | grep -i close_wait | grep 127.0.0.1:8080 | wc -l 5.) Note that initially there are 0. 6.) Note that after the server is running for awhile there may be 100-200 matches 7.) Note that even after the server finishes working (do top or something to see that everything is done), There should still be 150 or so CLOSE_WAIT sockets open. 8.) Note that these CLOSE_WAIT items will stay there for quite awhile (minutes usually) and then evenually they will go to 0. Also, if you shut down JBoss they should go to 0 immediately.

Sending multiple requests from a WS client and using fastinfoset caused an increase of sockets in a CLOSE_WAIT state and incorrect shutdown. This issue was fixed by introducing the org.jboss.ws.client.remoting.disconnect.after.use JVM property, which causes the client remote to disconnect immediately. This property is enabled by default. If you disable it, HttpURLConnections remain open.
