Neil,

Now (as I understand your reply) just one explanation: a lot of us are
Linux guys and ofc will understand the idea and the above code; those
who are not, can only just reboot with the power-button and must wait for
a real fix of the proc or the kernel;

the output of 'ps --no-heading -C events/0 -o time' is the actual
consumed CPU time of the proc events/0:

# ps --no-heading -C events/0 -o time
00:01:17

and the awk-scripts brings this value into seconds only form:

# ps --no-heading -C events/0 -o time | awk -F : '{print $1*3600+$2*60+$3}'
77

a while-loop does this calculation every 600 seconds...

one could add a threshold, let's say 777 secs, and when this is reached
the FR reboots (just in the middle of a phone call to your best love :-))
