    <p>I'm taking a shot in the dark with this one but I've been experiencing an issue that I'm hoping someone might have come across before...My client makes a server call which pretty much just grabs data from a Sql server DB and returns it to my client however sometimes the client never receives a response from the Server. I put a bunch of logging in and the very last line of server side code is executed but still, the client never receives the response and as a result gets stuck "PROCESSING"... I added a WCF trace and monitored it using the Service Trace Viewer. </p> <p><img src="https://i.stack.imgur.com/R2A49.png" alt="WCF Activity Trace"></p> <p>And I'm seeing exceptions in the Activity logs that contain the following text:</p> <pre><code> &lt;E2ETraceEvent xmlns="http://schemas.microsoft.com/2004/06/E2ETraceEvent"&gt; &lt;System xmlns="http://schemas.microsoft.com/2004/06/windows/eventlog/system"&gt; &lt;EventID&gt;131075&lt;/EventID&gt; &lt;Type&gt;3&lt;/Type&gt; &lt;SubType Name="Error"&gt;0&lt;/SubType&gt; &lt;Level&gt;2&lt;/Level&gt; &lt;TimeCreated SystemTime="2013-06-11T19:38:52.8094768Z" /&gt; &lt;Source Name="System.ServiceModel" /&gt; &lt;Correlation ActivityID="{a3b3598e-8ce1-4afc-8cf2-89c6fa505061}" /&gt; &lt;Execution ProcessName="TwoFour.WCF.App" ProcessID="5056" ThreadID="111" /&gt; &lt;Channel /&gt; &lt;Computer&gt;VA3WEB-REMEDY01&lt;/Computer&gt; &lt;/System&gt; &lt;ApplicationData&gt; &lt;TraceData&gt; &lt;DataItem&gt; &lt;TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Error"&gt; &lt;TraceIdentifier&gt;http://msdn.microsoft.com/en-US/library/System.ServiceModel.Diagnostics.ThrowingException.aspx&lt;/TraceIdentifier&gt; &lt;Description&gt;Throwing an exception.&lt;/Description&gt; &lt;AppDomain&gt;TwoFour.WCF.App.exe&lt;/AppDomain&gt; &lt;Exception&gt; &lt;ExceptionType&gt;System.ServiceModel.CommunicationException, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089&lt;/ExceptionType&gt; &lt;Message&gt;The socket connection was aborted.

Any information would be greatly appreciated.</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
