httpd on Win XP transmit garbage if size >32K

           Summary: httpd on Win XP transmit garbage if size >32K
           Product: Apache httpd-1.3
           Version: 1.3.24
          Platform: PC
               URL: 
http://pmcferrin.ugate.net:81/photos/Live_Nature/
        OS/Version: Windows XP
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Other
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: paulmcferrin@worldnet.att.net

In moving my existing Apache 1.3.22 [bindist] (Cygwin based) to my Windows XP platform (Cygwin based), I have encountered two problems. The first problem (can't fork) was due to a cygwin problem that required me to rebase all of the DLLs. After rebasing the DLLs, the httpd now starts. First problem is solved.

Second problem...

When viewing any page that has elements over approx 32KB in size, all bytes beyond the 32KB boundary is garbage. If you have images on the page, only the 1st 32KB of the image is intact. The rest is garbage. The total downloaded image size is correct! If you download a file (http) and save it, only the 1st 32KB will be correct, the remainder of correct size will be garbage.

When I compare the download images & files with the source file, the diffeence begins at byte offset 32769. Files & elemments less than 32KB in size are loaded correctly. If the HTML page itself is over 32KB (no graphics), the page is corrupted beyond the 32KB boundary.

I then upgraded to the latest httpd release for Cygwin [bindist] (1.3.24) and the same problem appears. When I look at the error_log file, there is nothing of consequence being logged. I'm running Cygwin DLL version 1.3.6.

At least one other user on the Cygwin mailing list is having the same problem with data corruption beyond 32K on Win XP. I have made several posts to the cygwin mailing lists but no one has taken the bite as it is not clear it is a Cygwin problem. This problem is present only on the Win XP system. I'm running the Professional version.

These images are loaded correctly when using the httpd server on my Win 98 system or if I point my browser to the hard disk.

In the first problem, the following rebase command was executed (a requirement):
