There is probably a problem going on there. I find it strange that you have so much cumulative CPU time on the httpd processes. To me, they look hung (in so far as I can tell). Since most apps are transactional in nature (i.e., individual requests being fulfilled rather quickly), you would expect to see the Apache processes using CPU, then giving it up rather quickly. Of course, other httpd processes will also pop in and out of CPU usage as individual requests pop in.
How long has this Apache/Tomcat been running? You might try a restart of both and see if the same behavior comes right back or if it takes time. You may have an issue in the app which is triggering a hang. Of course, on a "pretty busy web server", you may get such cumulative times, but you should still see httpd processes popping in and out of CPU usage as they handle their respective requests. If the same PIDs sit there pegging the CPU incessently, you most likely have an issue.
