Me again... :) I managed to narrow down the area where things go wrong: Undeployment.
When a node is shut down with ctrl+c JBoss undeploys all the MBeans. Naturally it also undeploys my custom MBean. What seems to go wrong here is that when it undeploys the ProyxFaxtoryHA it does not only remove the one instance of the service from the DistributedReplicantManager but rather it removes them all.. Why do I believe this? I tried to put a sleep() command in the stop() method of my MBean so I had time to reload the listContent() view of the DistributedReplicantManager while the MBean was being undeployed. I discovered that _all_ instances of the arsenal.at:service=WorkflowController disappear as soon as the _first_ cluster node starts to undeploy the MBean (since the ProxyFactoryHA depends on that MBean I assume that it is removed before the stop() method on my MBean is called, and the sleep() gives me time to reload the view)... Consequently I tested a node failure by pulling the network cable on one of the nodes.. and it _worked_ .. the cluster discovered the dead member.. the view in listContent() lost only the service instance of the failed node. All subsequent invocations were passed to the living node. No Exceptions. I restarted the "dead" node and reconnected it to the network. It re-joined the cluster, and the invocations were distributed among the two nodes again. That's why I am fairly certain that things go wrong during undeployment. Perhaps now the situation is clearer and someone can give me a hint on this? Thanks a lot. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3927111#3927111 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3927111 ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
