MM Restarts on Pi4

sdetweil

@thad do

ls ~/.pm2

notice the .(dot) in front of pm2

looks like a disk corruption

how old is the SD card?

@sdetweil

pi@raspberrypi:~ $ ls ~/.pm2
dump.pm2 dump.pm2.bak logs module_conf.json modules pids pm2.log pub.sock rpc.sock touch

The SD card is probably a couple of years old.

@thad weird…

looks like pm2 is messed up

let’s do this

pm2 delete 0

to get rid of the saved task

them

pm2 unstartup

it will give u a command to copy/paste on the command line. do that…

then reboot.

pm2 is gone, so nothing will start

then run the fixuppm2 script from my scripts repo

https://github.com/sdetweil/MagicMirror_scripts

see the last entry copy/paste

MagicMirror should start

then reboot to see if pm2 starts mm at boot time

Good news, bad news…

Everything worked great until the last reboot. Post reboot, the MM restarting every minute starts again.

Another observation, while running the fixuppm2 script I get those odd warnings:
Accessing non-existent property ‘pwd’ of module exports inside circular dependency

Several months ago, January I think, you helped me with the gpu related restarting. Once we got that working I don’t think the Pi4 rebooted until last week. I have very stable power and it’s plugged into a UPS. I think this problem may have been laying dormant for a long time.

If you have other things you want me to try, let me know. For right now I have it working and I know the procedure to get it working again if I have to reboot for any reason.
