Exception when size is too big

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!

Die meisten von uns sprechen kein Deutsch. Es würde helfen, wenn Sie eine Übersetzung zur Verfügung gestellt.

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

System.ServiceModel.CommunicationException was caught

i think this is the exception in english:

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?

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

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?

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.

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

<system.web>
    <httpRuntime maxRequestLength="204800" executionTimeout="7200"/>

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!

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.
