      @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:

      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 I really have no idea where you are.

        Flash the legacy image
        Boot , don’t update
        Run my install script

          @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?

                    If I connect an SSD via the data port and remove the SIM, will the 0 boot from the SSD? Or is there a way to configure the SIM to have it switch to the SSD or something?

                      @davidgagne pi 0 doesnt support boot from ssd/usb

                      you can make a hybrid, boot from read only sd , run from ssd
