Exception when size is too big

Question

Hello together i have a problem with my WCF Service when the size is to big. I get following exception: 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. Inner Exception: Von der Übertragungsverbindung können keine Daten gelesen werden: Eine vorhandene Verbindung wurde vom Remotehost geschlossen. If i try to debug into my Wcf Service i see that it already fails before i get into my method of the Wcf Service. This is the method the exception is thrown but i never come in my SaveLastVersion-method the exception is thrown before: client.SaveLastVersion(lastV dateiToByte); Size of lastV: 23669380 (byte[23669380 ]) Size of dateiTByte: 3119608 ([byte[3119608]) I searched a long time but i cant get the right answer to solve my problem. Thanks for helping!

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.
