    @davidgagne that’s why the MagicMirror out log is empty, as the app name is pm2

    How did you create that?

    And the number under the curly circle next to status is the number of times it has restarted

      @sdetweil I mean … I have no idea how I created that. I simply followed the same steps as last time and then executed a few of the commands you told me, e.g. pm2 delete 0, pm2 delete 1, and pm2 save -f. Then I called your fix’em up script:

      bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"
      the log will be saved in /home/dvg/MagicMirror/installers/pm2_setup.log
      

      and after that I called pm2 save followed by pm2 start MagicMirror and then installers/mm.sh & when I was asking you about my cluttered Terminal screen.

      Then I called pm2 restart MagicMirror which told me:

      Use --update-env to update environment variables
      [PM2][ERROR] Process or Namespace MagicMirror not found
      

      So then I called npm start & which gave me

      [1] 12338
      
      > magicmirror@2.28.0 start
      > ./run-start.sh $1
      
      ./run-start.sh: line 79: 11841 Killed                  node serveronly
      

      So I did a sudo reboot and everything seemed to be working fine. But my out log was empty so I called npm run server at your direction, and here we are.

        @davidgagne the log is empty cause the pm2 app name is used for file names

          @sdetweil Hm. I do have a file /.pm2/pm2.log that’s filled with thousands of these:

          2024-08-04T00:35:12: PM2 log: App [MagicMirror:1] exited with code [1] via signal [SIGINT]
          2024-08-04T00:35:13: PM2 log: App [MagicMirror:1] starting in -fork mode-

          2024-08-04T00:35:25: PM2 log: App [MagicMirror:1] online
          

          The last entry in that file is from 2024-08-04T21:22:04, which is around/about the last time I rebooted the Pi.

          The tail of that log file looks like this:

          2024-08-04T21:16:54: PM2 log: pid=3352 msg=failed to kill - retrying in 100ms

          And in the /.pm2/logs/ directory I have MagicMirror-error.log, MagicMirror-out.log, pm2-error.log, and pm2-out.log.

          That last one appears to contain what I would have expected to see in the MM-out.log.

          I am not opposed to flashing the drive and starting from scratch if you think I should.

              @davidgagne The Pi Zero has 512KB memory, the default swapfile size setting is 100KB, and the swapfile is located on the SDcard which is not very fast.

              I would suggest changing the swapfile size to 2048KB by editing /etc/dphys-swapfile and changing CONF_SWAPSIZE=100 to CONF_SWAPSIZE=2048.

              You might consider moving from the SDcard to an SSD which will provide quicker data access and improved security against SDcard failure.

              Lastly, you might consider changing from a Pi Zero to a Pi Zero 2 or something with more processing power. I use a Pi 3 Model A+ with a USB attached SSD and 2048GB swapfile size.

                @butchkemper my install script increases the swap file size if its small (200meg or less).

                  @sdetweil @butchkemper I just checked that file and it has no CONF_SWAPSIZE variable.

                  There is a SWAPSIZE variable set to 1024.

                  Is there a chance that @sdetweil’s script misnamed that variable?
