Hi Guys, We're seeing some cluster recoverability issues. We're using JBoss 4.0.5 in a clustered configuration (just a tw For the most part, everything works great. A while back we had a quartz job that caused an OutOfMemoryException in one node of the cluster, after which, the whole cluster fell apart. To try and reproduce this situation, I've created an admin only URL where I can cause one of the following two things on a single node of the cluster : 1) call system.exit 2) start a quartz job that purposefully runs the node out of memory. I just ran a small test with scenario #1, and I can reproduce the problem. Basically, I hit the URL on node1, causing the JVM to exit. After that, node2 is still present, but the application is hamstrung (we get exceptions on any operation which touch JMS). I've watched the logs on node2 when I cause node1 to die, and I do see the JMS queues/etc migrate from node1 (now dead) to node2. Here are the migration type log messages (immediately after node1 has died) : | 2007-09-21 11:58:20,703 [JMSContainerInvoker(ReportServicePreExecutionMdb) Reconnect] [] [] INFO
