MM freeze over night

[MajorC]

Hello,

my MM freezes over night. I suspected the SD card or one of the modules. So I bought a new SD card and the original Pi power supply and proceeded step by step:

1. only Raspberry Pi OS 5.4.51 installed -> runs 48h without problems

2. MM via the installation script of @sdetweil

-> MM runs for about 12 hours then the PI obviously loses the wifi connection or something else happend and the whole OS freezes. I still see the MM on the monitor, but:

• in the terminal I can still execute commands
  or
• the whole OS is frozen, not even the seconds are running

My question, what is the best way to proceed? Where can I view which logs?

[MajorC]

I now have a clean OS installation and a clean MM installation. Stopped MM with

pm2 stop MagicMirror

and see, what it is doing over night.

@MajorC which modules are you running? I had that with conflicting modules and activated one by one to find the culprit. It was a Google maps module in my case.

Good morning, with a clean OS and a clean but stopped MagicMirror my Raspberry ran for 48h without any freeze or wifi problem or what so ever. Even after the 48h I could access the OS via SSH.

Now I rebooted the system, MagicMirror with only the default modules without any changes are running. Let’s see what is in the log’s after 48h.

I am still looking for help, where I can find the right logs to look into.

Thank you.

My MM was running now for 48h without freezing. I don’t know what happened the last couple of times. Thank you to @Tribun ! I checked all the logs and found no problem. I will now start to install the first modules and see what’s going on.
