I am been using a raspbery pi 3 successfully for a few years to run Node Red for home automation. The Pi also hosts MQTT mosquito. I am not using any GPIO pins. For some reason today the Pi is throwing the following errors: "Recovery application crashed. sh: can't access tty; job control turned off." I have been unable to get this to clear up by powering the down the Pi and then bringking it back up. Can some assist me with this issue? It would be greatly appreciated.
