I encountered a similar issue of numerous Httpd processes spawning b/c of
Tomcat.  The issue for me was that Tomcat was running out of memory, and
Httpd for some reason thought spawning a bunch a threads would help ;)

Do you know how much memory these instances of Tomcat are using?  The
default JVM memory is ridiculously low and requires the adjustment to higher
maximum value for production servers.

Grep "heap" catalina.out to see if tomcat is indeed running out of memory.
