Default RE: The underlying connection was closed

This appear to be a webservices error. There is a tool you can use to track the activity of the service call (TcpTrace).

Check out this page for more detail http://connectionstringexamples.com/...nection-closed.

Thumbs up RE: The underlying connection was closed

It may also due to limit on DataContractSerializer with no. of items to serialize/deserialize

You can confirm this by turning on WCF logging with below entries:

<diagnostics>
<messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtTransportLevel="true" logMessagesAtServiceLevel="true" />
</diagnostics>

<system.diagnostics>
<sources>
<source name="System.ServiceModel" switchValue="All">
<listeners>
<add name="messages"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData="c:\logs\messages.svclog" />
</listeners>
</source>
</sources>
</system.diagnostics>

If it's due to that limitation, you can increase the limit as given in this link:

All the best..
