Exception when size is too big

Good to hear that you figured it out.

I think there are relevant articles in this web site. I think that one reason the size limit is small is to limit the effectiveness of a Denial of Service attack. You should look for relevant articles.

Sorry for your help but i resolved the problem now.
i needed to put in following in the web.config:


   

The maxRequestLength in IIS 6 is set to 4MB but you do not see this section in your web.config you have to put it in by hand.
In my opinion 4Mb is someting like a bad joke... ^^

Thanks for helping!

I cannot help beyond here; I don't have the experience to know what to do. My guess is that there is little anyone here can help; you need to do some analysis of your system. Perhaps someone can help you to do the analysis.

The exception is thrown either when i install my apllication which uses an IIS on a real Webserver but also when i
test it on my local machine (IIS also on my local machine). Perhaps this helps?

Thank you for your answer. What could that be for example?
is it possible that i have to change something on my IIS?

Danke. Das hilft.

Thank you. That helps.

Probably the important part is the part that says that an "existing connection was forcibly closed by the remote host". So there seems to be something happening at the other end. It might be a hardware problem with the connection or something else. Does it seem reasonable that that could be the problem?

i think this is the exception in english:

Message = "The underlying connection was closed: An unexpected error occurred on a receive."

This is the wohle Exception, before i try to translate it into english:

System.ServiceModel.CommunicationException was caught
  Message=Fehler beim Empfangen der HTTP-Antwort für http://localhost:52277/ServiceKalkulation.svc. Die Ursache kann sein, dass die Dienstendpunktbindung kein HTTP-Protokoll verwendet. Eine andere mögliche Ursache ist, dass der HTTP-Anforderungskontext vom Server abgebrochen wird (vermutlich auf das Herunterfahren des Diensts zurückzuführen). Weitere Informationen finden Sie in den Serverprotokollen.
