CommunicationObjectFaultedException occurring only in test environment

I have a WCF service than in my development and production environments works without a开发者_StackOverflowny trouble but in my test environment it will occasionally throw a CommunicationObjectFaultedException. This has been very difficult to track down but it seems to happen only after going a long time with out calling it.

The client is a web applictaion running on two load balanced servers, the WCF service is hosted in IIS and running on two load balanced servers.

There is no difference in the WCF configuration between the three environments so I believe there must be something different in the way the servers are set up. What are some things I can ask my server admins to check? (I don't have proper access to these servers to check stuff myself).

You may want to enable tracing on the server in order to get more detailed error information. Can you ask your admins to enable that?

<configuration>
   <system.diagnostics>
      <sources>
            <source name="System.ServiceModel" 
                    switchValue="Information, ActivityTracing"
                    propagateActivity="true">
            <listeners>
               <add name="traceListener" 
                   type="System.Diagnostics.XmlWriterTraceListener" 
                   initializeData= "c:\log\Traces.svclog" />
            </listeners>
         </source>
      </sources>
   </system.diagnostics>
</configuration>

Good luck!
