Apache question ... 8k file?

Folks:

Had a weird situation the other day ... someone notified me that a
single page on my website wasn't displaying.  No specific error, but no
page either.

I went to the page and saw the same thing.  I couldn't figure it out.
So I checked the main error log for apache ... and I saw the
following... "child pid 14075 exit signal Segmentation fault (11)"

Unfortunately, I couldn't figure out what was causing the segfault.

Upon some investigation, I noticed that the file was exactly 8192 bytes
long.  On a lark, I manually edited the file to change it's size to 8193
(added a blank).

The page displayed fine.

When I removed the extra blank, so the file was 8192 bytes again ... it
segfaulted when displayed.

The system is a Redhat 7.3 with Apache 1.3.27 (yeah, I know it's old ...
but it works {mostly}).

The pages that are being served are static and are on a nfs mount (if
that makes any difference).

The only module I'm using is mod_layout so I can add some content to
every page.

Any suggestions on how to figure out what is causing the segfault on an
8k file?

Thanks!
