WCF Socket Problem

Question

I am using a WCF application which is hosted as a Windows service. This application is accessing an email account and downloading mails that have a CSV attached to it.

But sometimes I am getting this exception:

10/1/2010 10:39:52 AM - 2 - System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine
   at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
   at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 size, SocketFlags socketFlags)
