[arm-allstar] system powering down

[David McGough]

Rick,

There is a script running on HamVoIP called the "shutdown monitor." This 
script looks at some RPi GPIO pins and if asserted will shutdown the 
system, giving the announcement you're indicating.  I've never had this 
script trigger inadvertently, however that would seem to be what you're 
seeing.  Are you using RPi GPIO pins? OR, is the RPi in a very hostile 
environment (e.g.: hot with RF at a broadcast site?)??

To disable this script, edit the /usr/local/etc/allstar.env file and on 
about line 41 you'll see:

export SHUTDOWN_MONITOR="enabled"

....change this to:

export SHUTDOWN_MONITOR="disabled"

....and save the file.  Then, look for the running shutdown monitor and 
kill it. This will keep you from having to reboot:

[root at RPi-Z2W etc]# ps axw | grep shutdown
  506 ?        S      0:00 /bin/bash /usr/local/sbin/shutdown_monitor.sh
 9452 pts/0    S+     0:00 grep shutdown
[root at RPi-Z2W etc]# kill 506
[root at RPi-Z2W etc]# ps axw | grep shutdown
 9454 pts/0    S+     0:00 grep shutdown


....This problem should be resolved.  Note that by editing the allstar.env 
file, this script won't get launched again, when the system is 
booted/rebooted.....Again, I'm curious how the GPIO pin could be 
inadvertently asserted?? ...I've never heard of this before?

I'm not sure what it is saying for ??????, almost sounds like 
"waffling".  Anyone know the cause?

thanks,
