Question:

Why do Mac OS X 10.5 clients stop receiving messages sent from the server?

Answer:

A number of changes were made to the AFP client in Mac OS X 10.5 that streamlined the network login process. The most obvious change is that a single process called NetAuthAgent initiates network logins for both SMB and AFP. Although a common UI and login process greatly improves usability this change created an unexpected problem. The NetAuthAgent terminates 2 minutes after a login. NetAuthAgent also launches an application called check_afp that is responsible for receiving messages from the server (among other things). In Mac OS X 10.5.0–10.5.6 when NetAuthAgent terminates so does the child check_afp process.

Apple resolved this problem in Mac OS X 10.5.7, released May 12, 2009.
