We are having a problem getting photon to shutdown using the ‘shutdown -b’
command. Here is the situation:
We have put ‘ph’ as the last line in the systinit file so the photon GUI
will start automatically. This is required as we are building a system that
starts automatically.
After the user logs in and attempts to go into a shell an run
‘shutdown -b’ as the superuser, the system hangs after doing a little work.
We cannot determine why this is happening. Has anyone else seen this
problem? If so what is the solution, or alternative way to boot/shutdown
automatically?

Which -b option/integer for Proc32 are you referring to? One of the
things I did not point out in the previous message is that when we
instantiate photon from the command line (after login) using ‘ph’, we can
use ‘shutdown -b’ fine. QNX runs through its shutdown sequence, terminates
applications and closes files safely. However, if the ‘ph’ is placed in the
sysinit file and login is performed via photon GUI, the system cannot
execute ‘shutdown -b’ correctly. At some point (no way of knowing where) it
hangs. We’ll work with the Proc32 ‘-b’ argument an see what we can come up
with. In the mean time, could you elaborate on the ‘-b’ issue with Proc32?
We appreciate the input!

‘-b’ options of Proc32? Other than that it should work.

I misunderstood the problem. I had a problem before and played with the -b
at random until it worked, but if it works outside photon…
I have set up several machines with ph as last line in sysinit without
problems.
Perhaps it is because I have also a tinit -t /dev/con1 & before it? But now
I am guessing wildly. Sorry.

How does the user log in? Is it when Photon starts up it has a login
window?
Do you start any tasks from the “/.photon/phapps” script?
When you say the system hangs is there anything in Photon functioning?
Can
you get to a shell and see whats running? Or can you look at whats running
from
another node?
A problem we have seen is where a task or shell has not fully terminated,
such as waiting
on its parents notification of death, that is may not allow the shutdown to
complete. Take
a look at situations where you have scripts, such as ‘ph’, starting other
scripts and some
where one of these is left running.
