Modify as appropriate. set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m to which i added another line: set JAVA_OPTS=%JAVA_OPTS% -XX:PermSize=256m -XX:MaxPermSize=1024m It's nice when information transforms to knowledge... ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963444#...
