I developed a WCF service and silverlight client, when I host this service in windows xp having iis 5.1, it is perfectly working as expected.

When i host in windows server 2003 R2 having iis 6, it is working for initial couple of minutes (approximately 20 mins) after that it stops working..

i am getting HTTP 500 when i access service.

The setting I have used are

Anonymous access and integrated authentication both are checked.

my service config is as follows

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="">
      <serviceMetadata httpGetEnabled="false"/>
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <customBinding>
    <binding name="SilverlightApplication1.Web.GetData.customBinding0">
      <binaryMessageEncoding/>
      <httpTransport/>
    </binding>
  </customBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
<services>
  <service name="SilverlightApplication1.Web.GetData">
    <endpoint address="" binding="customBinding" bindingConfiguration="SilverlightApplication1.Web.GetData.customBinding0" contract="SilverlightApplication1.Web.GetData"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
  </service>
</services>

my silverlight client config is 

<client>
        <endpoint address="----/InternalBorrow/GetData.svc"
            binding="customBinding" bindingConfiguration="CustomBinding_GetData"
            contract="ServiceReference1.GetData" name="CustomBinding_GetData" />
    </client>

can any body help me to trouble shoot my problem?

the exception i am getting is

I experienced a similar issue when we were running a .NET 4.0 web application in the same app pool as web service configured to use a lower version of .NET. Make sure you are not mixing ASP .NET versions in the same application pool on the server.

Are there any errors or warnings showing up in the web server's event viewer logs that would provide you with more information about the issue?
