2.0.44 (and earlier) fail to serve .jpg files on RedHat 7.3

           Summary: 2.0.44 (and earlier) fail to serve .jpg files on RedHat
                    7.3
           Product: Apache httpd-2.0
           Version: 2.0.44
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Core
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: [EMAIL PROTECTED]


In short, a RedHat 7.3 system I have with 2.0.44 installed refuses to serve .jpg
files but will serve other types without problems (.gif, .html, etc). I've also
seen this behavior occur with 2.0.39 as well under RH 7.3. Nothing is logged
about the request in the access or error logs although /server-status does show
the request being processed.

I have several other systems running RH 7.1 and RH 8.0 that do not exhibit this
problem with httpd 2 built the same way (built with:  ./configure
--prefix=/usr/local/image-server --disable-autoindex --disable-cgid
--disable-cgi --disable-userdir). Also 1.3.27 on the same RH7.3 system serves
the image just fine.

A HEAD of the image results in:

200 OK
Connection: close
Date: Fri, 28 Feb 2003 16:52:23 GMT
Accept-Ranges: bytes
ETag: "19319b-29ad-1f466980"

But if I use wget I see:

Resolving host.example.com... done.

HTTP request sent, awaiting response... 200 OK

11:52:01 (0.00 B/s) - Connection closed at byte 0. Retrying.

and then repeats the above until I Ctrl-C

Mozilla reports that it couldn't be displayed due to errors in the file and IE
gives a broken image tag.

Again there is nothing logged in the access or error logs and various other file
types work without problems. It's just the jpegs that fail.

My httpd.conf is an almost verbatim copy of the bundled highperformance.conf
(only the paths for docroot and logging have been changed, and the port set to 
8000)

A strace of the process during one such request shows:

If there's any additional information I can provide you with to help track this
down, please let me know.
