Hi! I just observed a strange thing with my configuration: JDK 1.5 JBoss AS 4.0.5 JBoss Profiler 1.0 With such configuration all the tests with a fresh out of box installation of JBoss and JBoss Profiler works fine but when i try to deploy my own application server is booting up and suddenly OutOfMemory error occur. When I comment entries about JBoss Profiler server is booting ok and application is deployed fine. I do test all was working fine, suddenly something goes wrong but cannot find what, in server log i have info about problems with deploying my application and thats all. My JBoss is after some modifications done by developers so maybe there can be a problem? Regards Marcin View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4199394#...
