Hello,

I have sent attachements concerning workers.properties an directives.

Our application is using webservers running behind a loadbalancer. Therefore it 
is a little bit difficult to find the exact statement that matches the stack 
trace of the tomcat. But there some stack traces in our Tomcats logfile and I 
will sent a you a typical error sequence from a modjk log file
