I guess I do not understand what you are asking. Is there a problem when you run with those settings? Or are you asking me to approve those settings? If so, see the presentation I provided a link to. Also, you must have already edited the run.conf file - the original Xmx size is 512m In general, never set Xmx larger than your RAM size. And never set it larger than what you really need (see my presentation to answer that). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4165419#...
