having the same problem, MM worked fine until my SD card was defect.
Did a fresh install with Raspian Buster and MM 2.8.0
since then the temp. is always near 80 degrees (showing the thermometer in the right corner).
Electron is taking 100% of processortime. (already using the fake kms driver).
taking the top off the case, and a heatsinks lowers temp a little bit, next step is a cooling fan, to see what that brings.
also the monitor on/off problem is back again, had that solved in the old situation.

Looks like the ANWB feed is not there anymore, the url is not valid anymore.
Module does not work anymore

be carefull with posting api keys, they may be payed by someone

looks like the ANWB doesnt provide the feed anymore
and i couldnt find on their website if it was changed.
my guess is that it is replaced for a payed version.
Removed it from my mirror, its not a module problem.

Had the same issue after updating a module in the remote control panel
This did solve it, tx sdetweil

It was a memory issue, but watchdog did not solve it.
my swap space of 100MB ran full within an hour or so, so i made it bigger to 150MB.
The MM ran for a week, and it froze again…
Made the swap space 2 GB ( twice the memory size of my Pi 3B), and it did not crash or freeze since i made that adjustment.
swapfile is around 220 MB at this moment, so 2 GB is a little overkill i guess
The pi does a scheduled reboot every morning. (As it has always done)

this MM, and the same pi (3B), has been running without any issues for nearly a year, problems started when using the last raspbian (Buster) version, and MM 2.8.0.
It has been running on stretch, but i am not sure about the MM version it was on before the sd card problem.
Will try watchdog, and report here if there are any improvements.
(btw Cron is already rebooting the pi every 24 Hrs).
As said before, the temperature issue was also not a problem on raspbian stretch, in nearly the same configuration of the same MM.

i wonder if a watchdog will be able to restart the pi when its locked up, i cant access it through SSH either when it happens.
my stats do not show a memory problem btw (19% free ram, but a very high cpu load), of course that is just before the screen froze…

active cooling fan lowered temp to around 60 degrees, crashes are not gone, but interval went down to once every 2-3 days. This does mean temp. was an issue, but there still is something wrong.

@madoXX
just did a fresh install of my magicmirror, because the sd card went corrupt.
during the install procedure it somehwere asked me if i want to autostart MagicMirror.
after that it started automatically after booting into the desktop first.
When trying to use pm2, it shows me the process is already running, but it’s name is MagicMirror , not mm.
MagicMirror version 2.8.0
