Console was non-responsive.  This time dump locked doing /usr so  
pretty much anything you try to run will block.  When the lockup  
happens when dump is running on my home dir (/u/yertle1) partition,  
as long as you don't need that partition you can log in and run any  
programs you like.  I have a service account whose home dir is in / 
var and was able to login that time to that account.  No such luck  
this time since any activity pretty much uses /usr.

Ping was responding (our monitoring didn't complain it was down).

The only thing I could do was break to debugger on the console.
