OS : Digital Unix 4.0 A
window manager : CDE
Platform : Alpha server 1000 A
Problem : Here's the sequence
1. Boot the server
2. wall command is working from console
3. let the server run for a few days
4. issue wall command from console
it takes the message text
after i hit cntrl-d to send the msg
the session hangs
5. I log in from another terminal and look for the wall
process. The process is uninterruptable U.
Scenerio: I have created a sh script to shutdown the server on sunday
and then reboot the server in single user mode to take a
full backup, after which init 3 brings the server to a multi
user + n/w mode.
shutdown fails after server is up for 7 days, because wall
is hanging so my script is no good. If the server is up for
a few hours the script works okay.

| 8695.1 | get a stack trace | SMURF::DUSTIN | Tue Feb 04 1997 11:49 | 9 | |
you need to trace the process using dbx on the kernel, ie.
# dbx -k /vmunix
set $pid=2174 (the pid of stuck process)

| 8695.2 | Found Patch to fix the problem | HEN::MEHTA | Fri Feb 07 1997 10:06 | 6 | |
I found a patch kit OSF400-107 that will ( hopefully ) fix my problem.
The problem is actually due to the wall and ntalkd processes that
remain hanging due to the abnormal termination of LAT sessions.
