Well, actually I haven't touched the settings which I used using Java 5.
But, I have tested the settings to some extent. My development environment
worked perfectly fine using the same memory and garbage collection settings,
also under heavy load (with jMeter). Are there any obvious mistakes?

Unfortunately I forgot to look at the gc.log (also I'm not sure how to
interpret it correctly), and it's overwritten when Tomcat is restarted, so
there's really nothing I can say about that. Do you suspect any problems
