Are you talking about the exception being thrown as a result of connection 
problems, or an exception propogated from the server to the client?

In the first instance, it is barely an exception at all. It is a normal 
condition and should be handled by the client very gracefully, and "at the 
most" provide a Warning in the logs ( I would probably just put an INFO ). 
The user will be notified of this. If a true fatal condition occurs, an Error 
is written to the log, the user is notified with something that makes more 
sense, and then a "Ok to Terminate" button.

In the second instance, the client should probably not receive a "Fatal" 
message at all. It makes users nervous to find Fatal stuff in their logs. If 
the server enters a fatal condition, the client application should be 
notified through a proper exception, and act gracefully to that. And no need 
to pollute the client log with anything but the same as above, a simple 

Sorry, but I fail to see how your use case invalidating Ceki's explanation.
