There was an error reading from the pipe: The pipe has been ended. (109, 0x6d)

Question

Hi,

We have a strange scenario.
When a service returns say 100 records all seems fine, but as soon as we try and return say, 30,000 records the following exception is encountered:

There was an error reading from the pipe: The pipe has been ended. (109, 0x6d)

This is the configuration settings we make use of:

    <bindings>  
      <netNamedPipeBinding>
        <binding name="netTcp" closeTimeout="00:10:00" openTimeout="00:10:00" transactionFlow ="true"
            maxBufferPoolSize="67108864" maxBufferSize="67108864" maxReceivedMessageSize="67108864">
          <readerQuotas maxArrayLength="67108864" maxStringContentLength="67108864" />
        </binding>      
      </netNamedPipeBinding>
    </bindings>

I have asked the developer to try the following bindings, still awaiting feedback.

    <bindings>   
      <netNamedPipeBinding>
        <binding name="netTcp" closeTimeout="00:10:00" openTimeout="00:10:00" transactionFlow ="true" receiveTimeout="00:10:00" sendTimeout="00:10:00"
            maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647" maxDepth="2147483647" />
        </binding>       
      </netNamedPipeBinding>
    </bindings>

Finally managed to get it working by making use of the following:

Note the bindings & behaviour configuration is required!

    <bindings>
      <netTcpBinding>
        <binding name="PortSharing" portSharingEnabled="true" maxBufferPoolSize="67108864" maxBufferSize="67108864" maxReceivedMessageSize="67108864" sendTimeout="00:02:00" receiveTimeout="00:02:00">
          <readerQuotas maxArrayLength="67108864" maxStringContentLength="67108864" />
        </binding>
      </netTcpBinding>
    </bindings>

    <behaviors>
      <endpointBehaviors>
        <behavior name="LargeItemGraph">
          <dataContractSerializer maxItemsInObjectGraph="67108864"/>
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="LargeItemGraph">
          <dataContractSerializer maxItemsInObjectGraph="67108864"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

Then also don't forget to assign these attributes to the actual service and client endpoints!!

    <client>
      <endpoint address="net.tcp://localhost/MyService"
                behaviorConfiguration="LargeItemGraph"
                binding="netTcpBinding"
                bindingConfiguration="PortSharing"
                contract="NameSpace.InterfaceName"
      />
    </client>



    <services>
      <service name="MyServiceName" behaviorConfiguration="LargeItemGraph">
        <endpoint address="net.tcp://localhost/MyServiceName"
                  binding="netTcpBinding"
                  bindingConfiguration="PortSharing"
                  contract="NameSpace.InterfaceName"
        />
      </service>
    </services>
