web_server.py stops working after several hours #35

Hello,

after a recent apt update && apt upgrade of all my sensor pi's, mostly RPi Zero2W's the webserver stops reading sensor data after a couple of hours or days.

The python Version I am using is 3.9.2 Pip check shows all deps up to date and met Funnily enough, the web server itself keeps running, the site is showing up with all zeros for every sensor If I login to the pi via ssh and start any other python script located in the same folder as the web_server.py, the output is normal and every sensor seems working...

Garage_error2

Garage_error

If I kill the process and restart web_server.py, everything is working fine for a couple of hours or days. I am using sandisk MicroSD with enough space on it and have swap to MicroSD disabled by default on all my machines. The RAM usage is constantly under 60MB, I am using the no desktop legacy 32bit Raspi OS.

I tried rebooting once a day but this did not solve the problem. `pi@garage:~/sensor/Python/Raspberry_Pi $ python3 web_server.py & [1] 2863 pi@garage:~/sensor/Python/Raspberry_Pi $ Starting the web server...
