AmxSid,
Your JVM is out of PermGen space. What Java version are you using (I assume a Sun JVM)? In the general case, recent Sun JVMs are pretty good at tuning themselves, so it is best not to try and tune it, as this may actually hamper and cause more problems than it solves. Having said that, I would remove the settings you have thus far and simply add -XX:MaxPermSize=128m The PermGen is the area reserved for reflective data, class objects and so forth. There are good introductory texts here http://java.sun.com/docs/performance/ Chris > I have the following error occuring. I really like XWIKI but this memory > issue is the only stumbling block.
