http://serverfault.com – I have a linux server with tomcat and MySql installed on it, with axis2 as well. At first I started with ~400MB allocated I deployed my project and still memory allocation was the same. But then I tried to use Log4j, which I think caused the problem. Problem is that not I have ~800MB allocated. Then I removed the service I deployed and still 800MB allocated. What have I done wrong? (HowTos)
