hi,
thank you for reply.
- does the same happen when you out a plain text file instead of mpeg, also
using appropriate content-type and --limit-rate?
i changed content-type to text/plain and renamed movie.mpg to movie.txt. No
behaviour change. If i abort download i will also get a 500.
- does it happen when you request static content using wget with --limit-rate?
no, if i just download a file for example http://127.0.0.1/movie.mpg all works
fine. Also if i abort download.
Please use following configuration:

This looks like server misconfig at first glance. In the BT there is nothing
about PHP. Combined with
the fact you find nothing in the error log, it might be not PHP.
How did you get that BT? Debug symbols should be used for PHP as well. And when
IIS starts, you should
attach the debugger to the clean PHP fcgi process, so then debugger takes over.
Some more points before i go try it
- does the same happen when you out a plain text file instead of mpeg, also
using appropriate content-
type and --limit-rate?
- does it happen when you request static content using wget with --limit-rate?
- please post the request/response headers
Thanks.

Every time i download index.php with following script i get an HTTP-Status 500
in Access Log.
[download.cmd]
"C:\Program Files (x86)\GnuWin32\bin\wget.exe" --limit-rate=40000
http://127.0.0.1/index.php
Multiple downloads cause the server to crash and return Status 500 for every
request (normal html pages, images, text files, ...).
Hope backtrace helps to find the problem.
