Unable to undeploy an application when it is running long time EJB calls. ------------------------------------------------------------------------- Key: WFLY-3836 URL: https://issues.jboss.org/browse/WFLY-3836 Project: WildFly Issue Type: Bug Components: Server Affects Versions: 8.1.0.Final Reporter: Dominik Pospisil Assignee: Jason Greene To update an application that is running, replace command from the management console is used. Therefore, first, the application needs to undeploy. After org.jboss.as.web.deployment.WebDeploymentService.doStop, ServerService Threads keep in WAITING state waiting all active ejb invocation to finish: "ServerService Thread Pool -- 116" prio=10 tid=0x00002b5cdce97000 nid=0x6d68 in Object.wait() [0x00002b5d10d0b000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00000005c5447f68> (a java.lang.Object) at java.lang.Object.wait(Object.java:503) at org.jboss.as.ejb3.component.interceptors.ShutDownInterceptorFactory.shutdown(ShutDownInterceptorFactory.java:111) - locked <0x00000005c5447f68> (a java.lang.Object) at org.jboss.as.ejb3.component.stateless.StatelessSessionComponent.stop(StatelessSessionComponent.java:135) at org.jboss.as.ee.component.ComponentStartService$2.run(ComponentStartService.java:72) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) at org.jboss.threads.JBossThread.run(JBossThread.java:122) Locked ownable synchronizers: - <0x00000005ba6adf98> (a java.util.concurrent.ThreadPoolExecutor$Worker) However, the application has some managed beans that do long time calls to a EJB method using remote invocation. DC and HC "hang" before the EJB call finish. JBoss could have a time out to the undeploy. Version-Release number of selected component (if applicable): JBoss EAP 6.1.1 Actual results: The application does not undeploy intermittently. DC and HC "hang" (they disconnect to each other) and it is necessary to restart all Hosts. Expected results: After some time waiting, the undeploy is forced to finish.
