Good news :)

That´s the Problem, I know about the pyramid capabilities of ECW, but I didn´t know GDAL and its caps until now. The answer will be somewhere in the net...

It is Apache! Because of that, its mystery! But I found a way to kill mapserv.exe remotely, with the RPC Tool taskkill.exe, which I found in the System-Directory of Win XP Prof. With the Force-Flag set there is nothing you cannot kill remotely on a Windose Box.

Thats what I thought, because there is no real OGC WM Service Application the market, which is able to serve large Image Raster Data. Image Web Server from ermapper.com is not really able to serve real OGC WMS, because of their own ECW as output Format.

Thanks for your spontanous help. On the postgis mailing list, no one answers as fast as here.
