(amb had a system exhibiting symptoms as well, but I'll supply data in
the hopes of being helpful.)
Possibly superfluous detail on circumstances of hangup:
tokata.mit.edu had its first-ever 9.4 problem last nite.
It is running 9.4.11 as of 7/14/05 22:30.
I was remotely logged in, came to work, did a console login and log out
and then went home. I noticed there were z-grams at home and since I'd
not intended to stay logged in, I clicked them away and logged out.
A little while later I realized I wanted to check someting, so I tried
to log in. My login session hung at "Running standard start-up
activities." Attempting to log in from another xterm failed. Logging
into athena.dialup, I did "athinfo tokata version" but it hung too.
Probably relevant stuff:
Today I came in, and the xlogin screen was frozen at 7/18/05 22:28.
The console window showed the following lines:
