On #4, this is the public interface that gets disconnected, correct?  AFTER the 
disconnect, try connecting (ping, telnet, ftp, etc.) from the remaining "up" 
server thru the private net interface (which should not have been disconnected) 
to the "down" server.
Just curious if the problem appears at the OS level, too...

[snip]

test:
1. sqlplus connect to cluster
2. determine which node I get connected to
3. run long running query on that node
4. inject a network failure on server interface the client is
   connected to
5. sessions to other node are locked up.
6. long running query fails, ends in ora-3113
7. watch both nodes stay locked up until network is restored

Can anyone verify that you have seen RAC recover from this sort of
failure?  Thanks for your help.
