UNSOLVED Issue with pm2: a wild Memory Access Error occured (Speicherzugriffsfehler)

[Stef]

am using pm2 to start my Magic Mirror 2 instance - everything works fine for a year now (i only had one issue with the logs, but i found the flush command, so that is not a problem anymore) and all of a sudden my pi is stuck the Desktop… The Magic Mirror won’t start…

Every command with pm2 gives me: “Speicherzugriffsfehler” - it’s german and stands for Memory Access Error.

Besides that, the Pi works fine.
I am still able to download and install software. vnc viewer and putty are still working
I’m on an Raspberry Pi 3 Model B Rev 1.2 which is auto rebooting every day at 3 am.

The Report is not working either:
$ pm2 report
Speicherzugriffsfehler

any ideas?

Thank you @sdetweil
but sadly it did not work:

bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"
the log will be saved in /home/pi/MagicMirror/installers/pm2_setup.log
bash: Zeile 188:  4212 Speicherzugriffsfehler  sudo npm uninstall $up -g pm2
bash: Zeile 188:  4296 Speicherzugriffsfehler  $pm2cmd delete MagicMirror > /dev/null 2>&1
bash: Zeile 188:  4342 Speicherzugriffsfehler  $pm2cmd start $HOME/MagicMirror/installers/$PM2_FILE
bash: Zeile 188:  4348 Speicherzugriffsfehler  $pm2cmd save

“Zeile” = Row
“Speicherzugriffsfehler” = Memory Access Error

The log says:

bummer. this is pointing to a bigger problem, SD cards are notorious for failing over time…
they have a fixed number of writable bits, but are write once… so that last place u wrote is marked as used.

when we start to see these weird behaviors, its been the SD card failing…
