DOs, NSConnections, rootObjects, and retain counts

[Christopher Roberts]

Hello, I'm curious about a problem I'm having with a client/server  
application using distributed objects. I have one server, with any  
number of clients connecting. The connections all establish fine, and  
all receive the proxy rootObject perfectly. All interaction while  
connected is fine.

When clients are connected, and the server shuts down, it invalidates  
the server connection, killing all client connections. Both sides  
receive notifications of this event, however, the retain count of the  
rootObject is not released properly, and thus is not deallocated  
before the program exits.

Like wise, with the server running, if a client dies, there is a 3 - 5  
second delay before the rootObject is released properly. I'm assuming  
the server shutdown problem is associated with this delay as well.  
What is causing this delay? This really doesn't cause any trouble with  
the function of the application, but I'm definitely not leaving it  
alone until I understand why this is happening.

Thanks,
Chris
