WCF maxStringContentLength Web.Config Overflow

I have developed a C# WCF web service successfully.  For the most part, it works fine.  However, when the XML content being passed to my web server exceeds 8192 bytes, the call to the WCF fails.  I have found numerous solutions on the web about this issue, but for some reason, I can't seem to correctly apply the changes to my environment.  I don't believe it's a client issue as the client calling my web service is a PERL script.  I even used WCF Service Configuration Editor as was mentioned in one posting, all to no avail.  Thanks for your help.

Here is the relevant section from my WEB.CONFIG that lives in the virtual directory on the server:

<system.serviceModel>
	<services>
		<service name="TaxonomyWCF">
			<endpoint address="http://myserver/TaxonomyTest/Taxonomy.svc" binding="basicHttpBinding" bindingConfiguration="largebuffers"/>
		</service>
	</services>
	<client>
		<endpoint address="http://myserver/TaxonomyTest/Taxonomy.svc" binding="basicHttpBinding" bindingConfiguration="largebuffers" name="TaxonomyEndpoint" kind="" endpointConfiguration="" contract="TaxonomyWCF.ITaxonomy"/>
	</client>
	<bindings>
		<basicHttpBinding>
			<binding name="largebuffers" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:10:00" sendTimeout="00:05:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="100000000" maxBufferPoolSize="100000000" maxReceivedMessageSize="100000000" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true">
				<readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
				<security mode="TransportCredentialOnly">
					<transport clientCredentialType="Ntlm"/>
				</security>
			</binding>
		</basicHttpBinding>
	</bindings>
	<behaviors>
		<serviceBehaviors>
			<behavior>
				<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
				<serviceMetadata httpGetEnabled="true"/>
				<!-- 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 -->
				<serviceDebug includeExceptionDetailInFaults="true"/>
			</behavior>
		</serviceBehaviors>
	</behaviors>
	<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
	<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>

Here is the C# interface definition file:

namespace TaxonomyWCF
{
    [ServiceContract]
    public interface ITaxonomy
    {

        [OperationContract]
        UpdateIssueResponse UpdateIssue(cqissue CQIssue);

        [OperationContract]
        UpdateTSRResponse UpdateTSR(cqtsr CQTSR);

    }
}

Try bumping up the maxBufferSize="100000000" maxBufferPoolSize="100000000" maxReceivedMessageSize="100000000" to 2147483647

Just a thought...

Darren,, the buffer I'm sending to the WCF is only 25,000 bytes long.  The issue, I'm sure, is that I've not connected the readerQuotas somehow to the actual service definition.  The error I am getting is still the maxContentStringLength > 8192.  Thanks again.  Do you have any WCF configurations with large buffers working?

Yes,

Although, I've recently joined a Java house so I'm not using it anymore.

You may have to change transferMode="Streaming" in the binding....

   <basicHttpBinding>
        <binding name="ExampleBinding" transferMode="Streaming"/>
      </basicHttpBinding>
