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

I have the following error occuring. I really like
XWIKI but this memory
issue is the only stumbling block. I would hate to have to move to daisycms
or jspwiki.
I have installed xwiki onto tomcat on Linux. Memory params are: -server
-Xms512m -Xmx768m -Xss512k -XX:+UseParallelGC
XWIKI config settings are out of the box ones.
I did upload an excel spreadsheet attachment and then decided to delete it.
I also tried to export to PDF, RTF etc. and left XWIKI running overnight
and got this problem in the morning.
