First, don't post screen shots of command line text - copy and paste the text into your post instead.
Second, showing the last few lines of the log where the server shut down doesn't ell us anything about the problem.Instead, either post the full server log file as an attachement, or include the console log output (though in your case that won't work since you are running JBoss AS as a service, unless you happened to redirect the console log to a file within the service init script).
Therefore, post the server.log file. It would help if you tar.gz it first.
