Re: commons-daemon on windows, not honoring JvmMx setting?
Depends on a number of factors, but with Java I typically not start to worry because of a few 100mb (especially since there are quite a few different metrics, real virtual or resident). But since your question is about the service runner I would definitely compare it to java.exe launcher and let us know. What command line arguments do you use and how many threads are active?
