Now that's interesting. I've been following this thread because I've just installed a new application on a Sun Cobalt (Apache/mod_webapp/Tomcat) server. It's the only application on the server, and nobody's using it yet, but the server monitor keeps mailing me about high memory usage.
But part of the Cobalt environment seems to be a repeating job that checks the web server status by trying to get a page every half-hour or so. The page isn't there, so it gets a 404, which is fine as far as the monitor is concerned, but I wonder what that's doing to my server resources? The answer, I imagine, is to make sure the dummy JSP is always present.

Time to read the conf file to see what we can do about 404 error documents. Sai.
