Your workers.properties don't look complete, for instance there is no worker.list in there, so all your worker definitions will not be functional.
Have a look at the various timeouts mod_jk provides, especially connect_timeout and reply_timeout. You could also use apaches builtin server-status and mod_jk status worker to get an idea, what the web server is actually working on. Finally with an increased jk log level of info, you might get additional information. The Apache error simply looks like the client/browser didn't wait until it fully received the response. That's normal, especially if responses take too long. This should result in a hanging site. Maybe you can describe more pricisely, what you mean by "site is hung up". - can you connect to apache - dies it log your requests into the access log - if you connect with a technical browser like curl or telnet, do you get any answers for your requests - will requests for static ressources (I mean requests that do not match your forwarding rules) still work? Although I don't think this is the source of your problems, httpd 2.0.46 is pretty outdated ...
