After upgrading I'm getting an error when I try to access the web UI (connection refused: tuplespace) :-
[Mon Jul 5 10:43:19 2010] [error] [client 10.6.254.211] Couldn't connect to server: Connection refused at /usr/local/airwave/lib/perl/Mercury/TupleSpace.pm line 71
On the AMP command line are you seeing the DISABLED message?
If so, enable AMP:
# amp_enable now
Wait a moment for the processes to come up. Try accessing the web UI again.
