[OpenAFS-devel] another weird afs client issue w/ cannot talk to server

[Derek Atkins]

Are the networks congested?  Is it possible that the server's
"WhoAreYou" is being blocked/dropped along the way?  I don't think
I've ever seen this with stable-IP machines (although I've definitely
seen it with machines that have been renumbered or mobile).  Albeit
I haven't seen it in a long while.
