What do you mean by free memory? Free RAM available in your PC or free space left in the java heap? Free RAM is not a very good indication of anything since the OS decides how to allocate that space, and what applications/services to run. You really should be looking at memory allocated to the java process to see how much memory the jboss app server is using.
