Howdy, As an aside, and this applies for windows as well as linux/solaris: -Xms and -Xmx control the size of the JVM heap. That's not the total JVM size. There are other spaces, e.g. the stack, symbol tables, and OS process overhead, that contribute to the overall process size.
How much they contribute depends on the OS version, JDK version, and other things, and is very difficult to predict precisely. You can measure it at any given point by comparing the output from an OS-level top (e.g. top on linux, or the task manager in windows) to the output of Runtime.getRuntime().totalMemory(). You will always see a difference. So if you're basing your assertion that -Xmx is ignored on the output of an OS-level tool, please rethink your assertion in light of the above. If you're basing it on the actual Runtime.totalMemory() output, then you are correct in saying you likely did not install tomcat correctly.
