Request Entity Too Large Even After Updating web.config

Question

I have a very annoying issue, where my WCF service orks fine for most requests, but for a particular large request, I am getting this error in my header:

HTTP/1.1 413 Request Entity Too Large

The request is welll under my specified maximum request length (2147483647) so I have no idea why this is happening.

These are the settings I added to my config file to overcome this, but nothing is working:

<httpRuntime maxRequestLength="2147483647" />

<behavior>
  <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>

<basicHttpBinding>
    <binding name="secureHttpBinding"
             maxBufferPoolSize="2147483647"
             maxReceivedMessageSize="2147483647"
             maxBufferSize="2147483647" 
             transferMode="Streamed">
        <readerQuotas 
          maxStringContentLength="2147483647"
          maxArrayLength="2147483647"
          maxBytesPerRead="2147483647"
          maxDepth="64"
          maxNameTableCharCount="2147483647"/>
    </binding>
</basicHttpBinding>

I have also included the entire config file below. Can anyone help me understand what is going wrong here?

I do not have access to the client which sends these messages in live, but I am testing using Soap UI.

Thank you

Here is an example message (wrapped in Soap envelope when being sent of course). You will notice that there are only 2 receivingAdviceItemContainmentLineItem elements, but the message which is giving me the problemn contains about 50. Note that the complete message which is not working is around 128kb in size when saved to a file:

Answer 1

I changed my web.config so that it looks like this:

<configuration>
  <connectionStrings>
    <add name="AccessConnectionString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Bassie\Desktop\AllwaysFresh Backoffice.mdb" />

  </connectionStrings>

        <behavior>
          <dataContractSerializer maxItemsInObjectGraph="2097151"/>
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->

          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->

      </service>
    </services>

    <bindings>  
      <basicHttpBinding>
        <binding maxBufferPoolSize="2097151"

        </binding>
      </basicHttpBinding>

    </bindings>

    <modules runAllManagedModulesForAllRequests="true" />
    <!--

        <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

</configuration>

And it now seems to work...

I changed various bits of the configuration file, none of which seem particularly relevant, so not sure why it works. If anyone could shed some light on this that would be great.
