Ian:


I also have crashes – more of the random type than regular, but my 
sloppy-but-it-generally-works solution may be helpful. I am running 
Motion on Raspberry Pi’s with one USB camera each, so the commands 
should be similar as you are running Ubuntu.


cron:

# Check for loss of an error every 10 minutes

*/10 * * * * /usr/bin/sh /home/pi/Scripts/Timeout.sh



Some extracts from my Timeout file (bash script):


####


tail /var/log/syslog | grep "Timeout waiting for hardware interrupt"

if [ $? -eq 0 ]

then

echo "Oh bother said Pooh!"

sudo shutdown -r now

else

echo "Nothing to look at, keep moving...."

fi



####



###########


tail /var/log/user.log | grep "Watchdog timeout did NOT restart"

if [ $? -eq 0 ]

then

echo "Oh mannnnnn!"

sudo shutdown -r now

else

echo "No problem-o."

fi


###########



And kind of as a side note:

###########

# Recycle Motion when goes off-line

# NOTE: at home directory: sudo chown pi:pi Scripts


# sudo service motion status | grep Active > $HOME/Scripts/Motion_Status.txt

# sudo service motion status | grep Active > 
/home/pi/Scripts/Motion_Status.txt

sudo service motion status | grep Active > /mnt/ramdisk/Motion_Status.txt

# Without the grep need to <q>uit manually


# tail $HOME/Scripts/Motion_Status.txt | grep running

tail /mnt/ramdisk/Motion_Status.txt | grep running


if [ $? -eq 0 ]

then

echo "Motion is running."

else

echo "WHOA!! Motion has a problem!!"

sudo service motion stop

sleep 3

sudo service motion start


fi

Couple of things with that snippet:

the use of grep to automatically quit the service inquiry


I sometimes found when using ‘sudo service restart motion’ it restarted 
too quickly. Using the stop, 3 second delay, and the the start worked 
better.


There are more options but I don’t think they’d appreciate me clogging 
the forum.


And yes, the echo’s are a little strange but come in handy for testing 
(manual run from Terminal).


HTH and Good Luck!
