In the future, I'm a lot more interested in keeping the machines in
clusters functional than I am in capturing debugging information; it's a
better idea to reboot than to leave it for a post-mortem, especially in
clusters that the developers don't frequent.
As for your specific failure, how long did you wait before killing X? It
sounds like you might have been running into the standard
AFS-hangs-when-network-goes-away failure to me. I really disbelieve that
you wouldn't see similar failures on Athena 9.
