将大（ish）字节数组传递给WCF服务失败，所有最大属性最大化

我正在调用WCF服务中的方法，并使用包含文件内容的byte []类型的属性传递DTO。这工作正常，直到文件达到大约3 MB，此时它失败。我能够找到的所有信息都是关于将配置属性设置为更大的值，但我已经将所有内容都放大了。这是来自我的网站配置文件：

<bindings>
  <wsHttpBinding>
    <binding name="dxWsBinding" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <security mode="None"  >
        <transport clientCredentialType="None" />
        <message establishSecurityContext="false" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

<behaviors>
  <endpointBehaviors>
    <behavior name="UserContextClientBehavior">
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
      <UserContextBehaviorExtension />
    </behavior>
  </endpointBehaviors>
</behaviors>

这是来自我的网络服务配置文件：

<behaviors>
  <serviceBehaviors>
    <behavior name="DefaultBehavior">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="True"/>
    </behavior>
    <behavior name="ErrorLoggerBehavior">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="True"/>
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
      <ErrorLogger logName="DXWcfErrorLog" />
    </behavior>
  </serviceBehaviors>
</behaviors>

<bindings>
  <wsHttpBinding>
    <binding name="dxWsBinding" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <security mode="None"  >
        <transport clientCredentialType="None" />
        <message establishSecurityContext="false" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

请注意，我不打算在生产中使用这些最大值，但我正在尝试一切以使其发挥作用。

当请求失败时，我的Web服务中看不到任何内容。我在两个配置文件中尝试了这个：

<system.diagnostics>
  <trace autoflush="true">
    <listeners>
    </listeners>
  </trace>
  <sources>
    <source name="System.ServiceModel"
            switchValue="Information, ActivityTracing"
            propagateActivity="true">
      <listeners>
        <add name="sdt"
             type="System.Diagnostics.XmlWriterTraceListener"
             initializeData= "WcfDetailTrace.svclog" />
      </listeners>
    </source>
  </sources>
</system.diagnostics>

但是当我打开Web服务日志文件时，根本没有失败请求的迹象。网站日志文件向我展示了我已经知道的内容。这是我在客户端获得的信息，即网站：

httpRuntime属性中还有一个maxRequestLength。

<system.web>
    <httpRuntime maxRequestLength="2097151" />
</system.web>
