Cool, Also, I'm examining my tomcat server.xml conf file for each instnace on each server. I am finding that Tomcat1 AJP connector is 8011, Tomcat2 AJP 8012, Tomcat3 AJP 8013, and Tomcat4 AJP 8014. So I will try and Add a maxThreads 600 on each of these.

This virtually eliminates the chance of a firewall dropping connections for you.
