I got the same problem the first time it hung this morning. I was connected 
to the server via ssh and when I did a su so that I can look at the logs or 
processes, it hang after I typed the su password. Once before, it also hang 
when I am directly connected to the server. So far I don't see anything 
that seems obvious. -hk
