Let me also suggest something else.

Let's suppose that your Tomcat is installed in the directory C:\Tomcat6, and let's call 
this directory "CATALINA_BASE" for now.

Under that directory, there is a directory "/webapps/", and undet that one there is 
(apparently) a directory "/rel/" with your current application.
In the directory /webapps/, at the same level as the directory /rel/, create a new 
directory "/freeze/", and in that directory place a html file "freeze.html".
It does not matter what the content of that html file is, just make it recognisable.

Next, in your Apache configuration, add the following lines :

ProxyPass /freeze/ http://localhost:8080/freeze/
ProxyPassReverse /freeze/ http://localhost:8080/freeze/

and restart Tomcat and Apache httpd.

Then, the next time Tomcat appears to freeze, try with a browser to access the "freeze" 
page, as :
and as

and let's see what happens.
