Jim,

  It is _possible_ that NFS is causing the shutdown process to hang=20
for a long time... if you could go into more detail about which machine
is NFS mounting what, that could help... but NFS should be causing
things to hang at a *different* part of the shutdown sequence.


  Based on the last few reports you have sent it is not completing the
shutdown process to the point that it should call halt -p, which would
call "/sbin/poweroff", which would invoke the kernel APM option I
mentioned, which would turn off the machine's power (if the power=20
supply and BIOS supports that operation).

  Since I don't have a Redhat machine handy, I can't check the shutdown
scripts myself but you say sometimes you get a:
  Sending processes the TERM signal...[hang]
but other times:
  System halted.

- Can you confirm that you tried the same command three times in a row
  and it did different things different times?

  (the command to try each time is "shutdown -h now")


Basically when "shutdown -h now" is run something like this should happen:
  Sending processes the TERM signal... done.
  Sending processes the KILL signal... done.
  Unmounting filesystems... done.  [this line could be multiple lines]
  System halted.

  It sounds like the "killall5" process is having problems... sometimes
but it is inconsistent.

The script I have here (on Debian) does the following:
=3D=3D=3D
# Kill all processes.
echo -n "Sending all processes the TERM signal... "
killall5 -15
echo "done."
sleep 5
echo -n "Sending all processes the KILL signal... "
killall5 -9
echo "done."
=3D=3D=3D

  As you can see the "sleep" for 5 seconds happens *after* the "done."
is printed... if the system hangs it would be inside killall5.

- Please look around in /etc/init.d/ for a script named "sendsigs" or run
    grep "TERM signal" /etc/init.d/*
  to figure out which script there does the TERM... if the working part of
  the script varies much from what is above paste your script here.

  If they are the same we need to figure out why killall5 is getting
stuck on your system... I have seen this before but I can not remember
what the reason was.

    TTFN,
      Mike Simons
