I'm working on a system that uses serial for two applications;
1) Reads in from a Maxbotix MB7389 ultrasonic sensor on pin 10 (TX) 2) Communicates (sends) measurement info to a household server through Xbee wireless radio modules
Somewhere along the line, the Raspberry Pi 3 began hanging on reboot, and tons of entries are being dumped into /var/log/daemon.log that I haven't seen before:
This is happening at all times that the system is booted, and it seems to be that the process is looping every 18 seconds or so, as can be seen by the timestamps. As far as I can tell, I don't have any software that's triggering this.
Has anyone come across issues that might be the cause of this? I can reimage the card, but would rather avoid it.
