Apache Error During Startup.

I get the following error when starting Apache: [alert] httpd: Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName /usr/sbin/apachectl start: httpd started /usr/sbin/webperfcachectl start: webperfcache started Apache appears to be launching but I am having some other strange issues and I am wondering if this could be the cause. I have done a google search for this error message, but I am still pretty unclear as to what it actually means. Any ideas? Thanks.
