Cannot find server or DNS Error - Ocassionally

I am new to the list, so this topic may already have been discussed. I am guessing that it probably wasn't since it hasn't made its way into any documentation yet. I am running php4.0.0 on Solaris 2.7 with Apache 1.3.12. I have a single script that parses the user input and includes some files into a template. Sort of like Apache SSI. Everything works great, however every so often I would get the following error Cannot find server or DNS Error. If I Refresh the page, or go back and re-click the same link the page will most likely load properly. I did some searching and found another post relating to the same problem and php3. Most of my browsing has been done with IE and am not sure if this is a browser dependant problem. I think its so rare that most people dismiss it. Anyone have any ideas?
