I'm not missing anything with logging.conf. As I mentioned above it is not 
just simply rewriting the logging configuration because I have to adapt the 
deployment process as well. Therefor I'd like to know in advance if you 
think that rewriting the logger would solve this issue.

And I'd like to know how this is possible at all in first place. I've other 
applications with much more users (but using Apache instead of Rocket) 
without this problem.
