Linux froze and got back working 5 days later, no reboot.
Hello my friends,
I've come across the weirdest of glitches.
I'm running a simple weather monitor (just temperature) on a Raspbeery Pi 3B (Raspbian Linux 4.14.98-v7+). It has a 3G modem that sends out simple packets to my server at home.
On june 5th I lost remote access to the device. Since it is located somewhere difficult to physically access, I couldn't manually reboot it.
To my surprise, on June 10th it got back to life. It has not registered a reboot! Here's the weird excerpt from the log at /var/log/messages:
It's as if the operating system froze for some reason and suddenly got back working 5 days later! Absolutely no reboot registered.
I have absolutely no other log.
Does anyone know what could have happened there?
