Someone correct me if I'm wrong, but mod_jk using the ajp13 and later protocols is supposed to leave connections open. One of the reasons behind the change from ajp12 to ajp13 was to get away from opening a connection to Tomcat for every servlet/jsp served by Tomcat.
If you're having trouble with lockups at a certain number of connections, you probably need to tune the Tomcat thread pool (server.xml), Apache/IIS, and/or the underlying operating system. Keep in mind that resources can be quickly exhausted when running IIS/Apache + mod_jk + Tomcat + your application + database + etc. all on one machine.
