I've just upgraded from JBoss AS 4.2 to 5.1 and have encountered a boot time issue that did not exist with 4.2. If I start the server while connected to my company's VPN, it takes 5:32 mins. With 4.2, it took about 1 min. If I start the server disconnected from the VPN, but still connected to internet (high speed cable), it takes about 1:40 mins. If I disable my network card, it takes 1:10 mins. I have not made any modifications to the server configuration that ships in the jboss-5.1.0.GA-jdk6.zip (also tried the jboss-5.1.0.GA.zip with the same results). Any ideas on why the server startup would be network sensitive? After turning on debug level logging for everything, I found these performance killers: 2010-02-25 12:56:31,003 DEBUG [org.jboss.management.j2ee.deployers.LocalJBossServerDomain] (main) handleNotification: javax.management.Notification[source=jboss.system:service=ServiceControl ler][type=org.jboss.system.ServiceMBean.start][message=] 2010-02-25 12:56:43,466 FINE [sun.rmi.transport.tcp] (RMI Scheduler(0)) RMI Scheduler(0): close connection 2010-02-25 12:56:43,481 FINE [sun.rmi.transport.tcp] (RMI TCP Connection(2)-3.7.149.84) RMI TCP Connection(2)-3.7.149.84: (port 1851) connection closed 2010-02-25 12:56:43,481 FINE [sun.rmi.transport.tcp] (RMI TCP Connection(2)-3.7.149.84) RMI TCP Connection(2)-3.7.149.84: close connection 2010-02-25 12:56:43,481 FINE [sun.rmi.transport.tcp] (RMI Scheduler(0)) RMI Scheduler(0): close connection 2010-02-25 12:56:43,481 FINE [sun.rmi.transport.tcp] (RMI TCP Connection(1)-3.7.149.84) RMI TCP Connection(1)-3.7.149.84: (port 1090) connection closed 2010-02-25 12:56:43,481 FINE [sun.rmi.transport.tcp] (RMI TCP Connection(1)-3.7.149.84) RMI TCP Connection(1)-3.7.149.84: close connection 2010-02-25 12:57:56,347 DEBUG [org.jboss.remoting.ServerInvoker] (main) SocketServerInvoker[HCU-C1WYGC1:4446] added org.jboss.profileservice.management.upload.remoting.DeployHandler@18309b 0 for subsystem 'DeploymentManager' As you can see, SocketServerInvoker takes over a minute. 2010-02-25 12:57:56,347 DEBUG [org.jboss.profileservice.management.ManagementViewImpl] (main) addTemplate: org.jboss.resource.deployers.management.DsDataSourceTemplate@98843 2010-02-25 12:57:56,347 DEBUG [org.jboss.profileservice.management.ManagementViewImpl] (main) addTemplate: org.jboss.resource.deployers.management.DsDataSourceTemplate@1d11c11 2010-02-25 12:59:21,346 DEBUG [org.jboss.profileservice.remoting.ProxyFactory] (main) Bound ProfileService proxy under: ProfileService 2010-02-25 12:59:21,424 DEBUG [org.jboss.profileservice.remoting.ProxyFactory] (main) Created ManagementView proxy Here, ProxyFactory takes over a minute 2010-02-25 12:59:28,508 DEBUG [org.jboss.aop.microcontainer.beans.GenericBeanAspectFactory] (main) Creating advice InvocationContextInterceptor with loader null 2010-02-25 12:59:32,573 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-14) Periodic recovery - second pass <Thu, 25 Feb 2010 12:59:32> 2010-02-25 12:59:32,589 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-14) AtomicActionRecoveryModule: Second pass 2010-02-25 13:00:24,142 DEBUG [org.apache.catalina.session.ManagerBase] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) Start expire sessions StandardManager at 1267131624142 sessioncount 0 Here, ManagerBase takes nearly a minute.
