I agree here. I do remember not being able to log in when i/o is completely swamped though. Maybe the problem is not so much 100% cpu usage but disk i/o. The box might be thrashing swap.
Oh, I missed that, we do use NFS badly(nfs mount home directory) in that box, the system became hard to login when lots of people works.
PS: I think, you know, root should be loginable in any condition unless the system is down. Shouldn't it?
Thanks, nate and Christopher
