The client that is referenced in the log file is multi-homed and sitting 
on three of the same LANs as the multi-homed server, so I know there's 
not a routing problem.  I have now added a NetInfo file to that client 
specifying the one interface I want the AFS traffic to flow on, so 
perhaps that will help.
