- Linux froze and got back working 5 days
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:
Jun 5 17:54:28 raspberrypi NetworkManager[345]: <info> [1559768068.0169] policy: set 'VIVO ZAP' (wwan0) as default for IPv4 routing and DNS

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?

I'm not saying it was aliens. But aliens.
It's practically impossible to know what happened without being there. It's possible it froze. Usually when things freeze we reboot, but maybe leaving a computer alone for 5 days does the trick also, impossible to tell without having seen what happened.
Maybe the network cut off, or the programming glitched out.

finally, proof! Linux IS better than windows, it self repairs and never needs rebooting, it just needs a day or 2 to troubleshoot the issues. :P
