I have apache 2.2.3. Not sure how to find the tomcat version. We use mod_proxy_ajp connector. During the test, I see high CPU usage and load on both appservers. So, I don't think it's the issue of everything going to one appserver.
With what i read around, increasing maxClients does not help much. Ofcourse I will try that but not that hopeful.
