There was a thread on this topic a bit back, http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= but it seemed to taper off without resolution. I think this is pretty important behaviour if applications are to be robust in the face of server restarts from whatever the cause, e.g. reconfiguring, server crash, host crash, maintenance, etc. In the very least it would be valuable if the precise behaviour of the system was well understood and document in the area.
I would be very appreciative of any light that can be shed on the subject.
