I unfortunately can't describe the exact situation that caused the
problems described below, because I was asleep when it happened and
woke up just as I got "Hit any key to start." I'll do my best.
I was logged in, running xscreensaver (with my screen locked) on
pit-manager. Suddenly (i.e. when I woke up :-), I turned around, and
I wasn't logged in anymore, and I was back at "Hit any key to start."
Don't know why. When I activated, I got the standard "Couldn't open
pty" error that you get from xlogin when the previous user of the
workstation was logged out abnormally. When I tried to log back in,
however, after typing my username and password, the xlogin and console
windows went away, and the load LED's on the front of the workstation
changed to 99, and the login process appeared to stop. I could still
move the mouse and get response from the mouse pointer, but I wasn't
being logged in. I went to another workstation and kinit'd with root
tickets and tried to klogin as root, and it didn't work, although the
workstation was pinging.
After rebooting, I found what appears to be a toehold coredump in
/usr/tmp/core.root, but I couldn't get a stack trace with either adb
or dbx. The core file is in /usr/tmp/core.toehold.0727 for anyone who
wants to look at it (pit exports NFS), and will stay there until it
gets reaped by the find scripts.
This is about all the data I've got, sorry.
