It seems it is not a mod_jk problem. mod_jk never shuts down Tomcat, but obviously your Tomcat shuts down during processing the request.
I would - update Tomcat *and* the service wrapper (jdvc) to the most recent patch update (e.g. Tomcat 5.5.33). - run Tomcat once without the service wrapper to decide, whether the problem comes from the wrapper or from Tomcat respectively your web application.
