Windows Communication Foundation Callbacks

Windows Communication Foundation Callbacks

I have a WCF callback server.The server invokes callbacks on registered
clients every 2 seconds. After few hours, the communication channel on the
client gets aborted and the client stops receiving callbacks. No exception
is thrown on the server side. If I restart the client without restarting
the server; all is well and the client starts to receive callbacks again.
I am not sure what is causing the callback channel on the client side to
abort. Note that no exception is thrown on the server side. Simply
restarting the client solves the problem and the client starts receiving
callbacks again, I am not sure as to why the callback channel on the
client side is getting aborted in the first place after a few hours. Any
suggestions will be most helpful. Thanks.
