beaglebone black services down

[casaln...@gmail.com]

Hello

I did seven  programas  in python  to measure the analogues inputs in my beaglebone black.I created one service for each script. I only have 4 signals connected to analogues inputs the other three are disconnect, but all services are running.

In my application I need all scripts are running automatically when the beaglebone black boot.

All scripts works well  for a few days measuring the values  in each analogue input , but , randomly  if there is a change in the  value in some input , this service fail  and is necessary start it  again. This happen in any input with a voltage , however , in the analogue inputs without  voltages, the services always are working.    

These are typical messages :
