Re: Apache 1.3.22 on cygwin under XP - loosing data

[<djnews@thedixons.com>]

I agree with what you found.  I now can get it to fail on plain html text as
well.
It usually starts to corrupt bits at around the 32K point.  I can pull up
hundreds
of thumbnails (~10-20K) without a problem. Out of hundreds of bigger
jpgs, 100% of the bad ones are >32K and 100% of the bad ones are <40K
(but it is not a clean break at 32K).  Also, text htmls go bad around the
same
point.  I have actually gotten it to pick up what looks like data from
another
file on disk!  I have seen that behavior 3 or 4 times.

I have tried the httpd binary that came with the cygwin distribution as well
as the build you can link to on the "Software" page.  They both fail.
I know they are the same revision (Apache/1.3.24 (cygwin)) but they are
wildly differrent sizes so I figured I'd try them both.

I have not yet download the win32 build at apache.org but I might try
that next.
