We have 3 Red Hat 4.4 AS Servers running RAC 10G. Today one of them had
load averages of over 160. But processors were 99% idle. None of the
RAC boxes were responding during this time. I was able to login fine
(my local user), and sudo su -. But when I tried to sudo su - oracle,
it just hung. Finally rebooting fixed the issue. As I have been
looking through log files, this is the only thing "weird" I have found.
We only use local authentication on the box.

Thanks for any help anyone can give.
