Hello,
I'm running Digital UNIX V4.0F on a DECStation 3000.
The system got into a weird state last week, in which it
still serves NFS and web as normal, but if I log in and type
"who" or "ps" or some other commands, my terminal session
hangs --- neither ^C nor ^Z can get the shell back.
I rebooted a few days back but the problem returned.
Searching through the list archives, I found the summary
to a similar question
http://www.ornl.gov/its/archives/mailing-lists/tru64-unix-managers/2000/05/msg00497.html
In the responses, someone suggested to trace the system calls
of ps, which I did. It gets stuck on a stat() call:
...
stat ("/dev/ttyp2", 0x11fffee90) =
And so I of course did "ls -l /dev/ttyp2" and promptly hung yet
another terminal session ... I can't run "lsof" to find out
the process using this tty either ...
Does this ring any bells? Maddeningly, I had this problem
years ago, but I can't recall how I fixed it, and I can't
find my notes!
Desperately yours,
-Steve
