RE: Session closed suddenly

There are a couple of possibilities:
. someone is invoking close() on the Connection
  that owns the Session
. the physical connection to the server has been lost. 
  This forces closure of the Sessions attached to the Connection

  You can verify if this is the case by registering
  an exception listener with the connection e.g.:
 
  connection.setExceptionListener(new ExceptionListener() {
         public void onException(JMSException exception) {
            exception.printStackTrace();
         }
  };
