hi, following szenario produces under heavy load exceptions:
Using JDK6, JBoss AS 4.2.3GA Start 2 instances with: ./run.sh -c all -b10.3.60.60 -DBind.address=10.3.60.60 and ./run.sh -c all -b10.3.60.57 -Dbind.address=10.3.60.57 after starting. Cluster will be formed ! Then start stress client with following code: try { Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); p.put(Context.URL_PKG_PREFIXES, "jboss.naming:org.jnp.interfaces"); p.put(Context.PROVIDER_URL, "10.3.60.57:1100,10.3.60.60:1100"); InitialContext ctx = new InitialContext(p); while (true) { try { HelloWorldEJBRemote ejb = (HelloWorldEJBRemote) ctx.lookup("HelloWorldEJB"); System.out.println(ejb.helloWorld("hello")); } catch (Exception ex) { ex.printStackTrace(); } } } catch (Exception ex) { ex.printStackTrace(); } then all will be ok. Shutdown one server. Test client is running and produce no exceptions. I start the stopped server to rejoin the cluster. but test-client produce following exceptions: java.lang.RuntimeException: cluster invocation failed, last exception was: at org.jboss.aspects.remoting.ClusterChooserInterceptor.invoke(ClusterChooserInterceptor.java:166) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.tx.ClientTxPropagationInterceptor.invoke(ClientTxPropagationInterceptor.java:67) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.security.SecurityClientInterceptor.invoke(SecurityClientInterceptor.java:53) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.remoting.ClusteredIsLocalInterceptor.invoke(ClusteredIsLocalInterceptor.java:55) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessClusteredProxy.invoke(StatelessClusteredProxy.java:112) at $Proxy1.helloWorld(Unknown Source) at Main.main(Main.java:26) Caused by: org.jboss.remoting.CannotConnectException: Can not get connection to server.
