The Web front-end server that is running Excel Services in SharePoint Server 2007 encounters a System.Threading.ThreadAbortException exception

The Web front-end server that is running Excel Services in Microsoft Office SharePoint Server 2007 encounters a System.Threading.ThreadAbortException exception, and all requests time out.

To work around this problem, change the Microsoft ASP.NET maxconnection property on the Web front-end server. For example, change the value to 10. To do this, follow these steps:

1. Locate the following folder:
   C:\Windows\Microsoft.NET\Framework\v.2.0.50727\CONFIG
2. In a text editor, open the Machine.config file, and then add the following section to the <configuration> tag before the <system.web> tag:

   <system.net>
   <connectionManagement>
   <add address="*" maxconnection="10" />
   </connectionManagement>
   </system.net>
   

3. Save the changes, and then close the file.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
