Does your MBD try to deploy before or after the HAPartition logging shown in your post from Monday? And does it try to deploy before or after the JMS server has started on the other node? If before, we've got a deployment ordering problem to solve. The TRACE logging you showed is normal stuff when a RPC comes in to HA-JNDI from another server and HA-JNDI can't find the requested binding locally. Another suggestion is to pass an IP address to -b when starting JBoss. If you don't, services bind to localhost, which could lead to strange behavior.
