Description:
------------
When I try to call the Copy(src,dest) function multiple times (More than 5 times) on remote files/images, my webserver crashes with bluescreen and the server reboots.
The script works if I call copy(src,dest) less than 5 times.

It crashes on this system:
Os: Windows XP Pro SP3
webserver: Apache 2.2.8
PHP: 5.2.6

It does not crash on the following system:
Os: Debian
webserver: Apache 2.0.53 
PHP: 4.3.10-8Debian

Best Regards Michael
