Hi, i have implemented the Project on a Raspberry Zero/W https://www.balena.io/blog/build-an-environment-and-air-quality-monitor-with-raspberry-pi/ Now my Rasp is constantly crashing after few days of working perfect

Got this error:

Hi @Gizimo -- one suggestion is to try upgrading the OS for your Pi Zero. The latest version in production (2.54.2+rev1 as I write this) enables support for zram, which may help performance in cases where resources are constrained. Can you give this a try and see how it works?
