Just to get better answers, can you provide some additional information, 
such as
- which Apache are you talking about (version) ?
- which Tomcat (version) ?
- how are they connected (connector ?)
- on which platform (OS) ?

Then anyway, as far as I know, /nothing/ is caching error messages.  In 
other words, if you get an error message, it means that some component 
really tries to get an answer from Tomcat, and is not getting any yet.

What you should really try, is to use the browser to access that same 
URL directly on Tomcat, without going through Apache, and see how long 
you have to wait there to get an answer after you start Tomcat.
In the Tomcat "server.xml", there is a <Connector> element for the 
direct HTTP port of Tomcat (probably on port 8080, or 8180). Note that 
port number.
Then try to point your browser directly to that port, with the same URL 
as you would use through Apache.
In other words, if your normal URL is
http://myhost.mycompany.com/myapp
then try
http://myhost.mycompany.com:8080/myapp

Again in other words, when Tomcat tells you in its logfile that it is 
started, it means that Tomcat itself is started.  But it does not 
necessarily mean that all the /applications/ that run under Tomcat are 
ready to answer requests.  That may take quite a bit longer.
Some applications may only get loaded and/or compiled when you call them 
for the first time.
