Thank you Emmanuel for the details. When I read your reply, a doubt popped up in my head. Hence I would like to clarify my doubt with you.
During the time of closing the the managed sessions(as explained above - closing all the pending sessions.), is there anything that the developer need to perform in order to prevent any new sessions from getting established. Will any new sessions prevent or delay graceful shut down of the service? Is such a mechanism already handled in mina framework? Richards Peter.
