You may be dealing with a request that crashes before any data
makes it into the logs.

Here's a trick I have used (posted Feb 10, 2008 by "Phantom"
in alt.apache.configuration):

ls -l `ps -C httpd h | sed -r "s/^\s*([0-9]+) .+$/\/proc\/\\1\/cwd/"`

which prints out the directory that each Apache worker thread is
accessing. If you can narrow it down to the pid, you can use lsof to
identify the particular file being being processed. Please keep us
posted!
