You already sent this reply - did you mean to add something?

What do you mean about truncating the Referer? I get the impression you think that the Referer is the thing after the "?" in the URL - it's not; that's the query string.

The Referer is a header in the request which contains the URL of the page the user was on when he clicked a link to your page (eg, if you are on a page with URL http://foo/bar and you click on a link with URL http://wibble/ then the request to wibble contains the header "Referer: http://foo/bar";.

The referer is usually generated automatically by the browser but it can be switched off or set to anything the client chooses - you have no guarantee that it will be present or accurate. So it's a bit strange that an apache process would regard it as an [error] that couldn't find it.

The error you are seeing appears in the apache error log. Therefore it is inserted there by something which hooks into the apache logging API. Usually, this is an apache module. Are you sure you don't have any extra modules added? 

- do "httpd -l" to check what modules are compiled in
- grep LoadModule httpd.conf to see what modules are loaded dynamically

What were the results of cross-checking the error and access logs?

PS - the correct English spelling of the active noun derived from the verb "to refer" is "referrer". However, whoever wrote the HTTP RFC spelt it wrongly as "Referer". This is now built into so much code on the web that it is probably easier to change the English language than the RFC...
