@the Sorry for the concerns. Uptime is of paramount importance and we have a zero-tolerance for unexpected reboots! If you enable remote syslog logging and are willing to share them with me, I can take a look. If you invite me to your site, I can look at a few more things, like temperature, etc. to make sure they are running in a normal environment. Please let me know which devices are rebooting if you invite me.
Currently, you can look at temperature with this via ssh:
for i in /sys/class/thermal/thermal_zone*/temp; do echo “Zone ${i##*/thermal_zone}: $(($(cat $i) / 1000)) C”; done
