This could happen in Apache 2 if the web server timed out before reading
the complete request.  (Apache 1.3 logs a 408; Apache 2 doesn't; Apache
trunk will log a 4xx of some sort depending on how much of the request
was read.)

If that's what's happening, it would indicate a problem outside of
Apache.  You could confirm it by backporting the fix from
https://issues.apache.org/bugzilla/show_bug.cgi?id=39785 so logging
would occur.  Then you might need to resort to packet tracing or
something like that to figure out exactly what's going on.
