I am having some hanging issues, but it doesn't crash, seems to revive again and i look in mod_jk.log and this is what i see exactly every 15 minutes:

Today I would test my new setup and run in some trouble. So be carefull 
what you are doing. I needed to change servlet.pl and jsp-vsite.pl stuff 
in order to get things the way I want them. If some of you is 
interrested in the pl files let me know. I'm still working in them since 
I really want that when a user has a webapp this webapp logs to the 
logsdirectory of that website under the name of webappname_log.txt  So 
I'm still working on some details. For the rest I just have some 
problems with JavaServerFaces and Some policy related stuff. But the 
basic it works and it works nice.
