hello,
on 2 of our servers we have same behavior.
we could not narrow down exactly, why script returns error 500 but we also have
iis + php readfile () in use.
hope you can reproduce & fix the bug soon,... if its really a bug.
regarding webserver crash with multiple downloads we can contribute following:
we have found a setting in iis. in fast-cgi settings, you can limit the "Rapid
Fails perMinute" by default it is 10.
if you increase it, there will be no error 500 anymore shown to the users.
but in log you still get errors.
it seems that iis kills all php-cgi.exe processes if there are too many fails
(error 500) in a specific time (perMinute).

I've just tried with apache and cli server and it's not reproduceable there
even
with a smaller bandwidth, so looks like it's stick to IIS. So no need you to do
it. Still unclear if it's readfile() so going to test your way now.

you can reproduce webserver crash with multiple downloads by following steps:
create file with following content:
[c:\tmp\wget.cmd]
"C:\Program Files (x86)\GnuWin32\bin\wget.exe" --limit-rate=20000
--server-response http://127.0.0.1/index.php
open cmd and typ in
cd c:\tmp
for /L %i in (0,1,10) do start wget.cmd %i
loop will start 10 cmd boxes and download the "movie.txt".
wait 10-20 seconds and interrupt download by closing all cmd windows (Close all
windows)
wait 1-2 seconds and start again 10 multiple downloads
open cmd typ in
cd c:\tmp
for /L %i in (0,1,10) do start wget.cmd %i
now all request will be answered with Status 500
c:\tmp>"C:\Program Files (x86)\GnuWin32\bin\wget.exe" --limit-rate=20000 --serve
r-response http://127.0.0.1/index.php
SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc
syswgetrc = C:\Program Files (x86)\GnuWin32/etc/wgetrc

hi,
sorry me too, overseen that you need --server-response option in wget.
good to see, that you can reproduce the behavior. :)
here is output of wget & description to reproduce the mutliple download crash:

That's not exactly what i wanted to see because you haven't used the
--server-response option with wget. But now I
see what I've overseen, consider this line in your wget output:
HTTP Anforderung gesendet, warte auf Antwort... 200 OK
I suppose that was something like "HTTP/1.1 200 OK" in the headers.
Also in your last post to see - that are not multiple downloads at the same,
but restarts on connection reset. The
status 500 in the logs indicates merely this, not the headers sent out. That's
what i get with curl and bandwith of
20K, were probably the same with wget and this bandwidth
$ curl -v --limit-rate 20k -o /dev/null http://127.0.0.1/65453/index.php

Just where curl exits, wget retries the download until it's worked, so infinite
tries by default. Testing with a
static file works. Anyway no crash yet, but now it's to figure out why the
connectio nreset happens. It could help
if you could test the same with apache or cli, too.
