Hi Phillip, please give some details of your application server deployment and the version of JBM. The possible reason of the "Cannot find session with id" is that the session has been closed before the 'commit' request arrives. How did you shutdown your application servers? and in what order? I'm asking these question because this might provide a clue to what has actually happened. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4232377#...
