Bug with Pi OS 64 and Raspberry Zero 2w

[Remy Lavabre]

Good morning all.

I have been using weewx for 3 years with pi os 32B without any problem with a pi zero w then 2w.

Since I switched to version 64B, I have had lots of incomprehensible crashes with the pi not responding and having to reset. weewx is not in question.

I tried to increase the swap, to switch to a 3A power supply, to go back to the non-gl drivers, nothing helped! 

Have you noticed this kind of thing in 64 bits? is there a way to fix the problem? thank you..

I'm using weewx on a Raspberry Pi 4B with Rasperry Pi OS 64 bit without any issues.

Are you trying to run a full desktop on the zero?

And why would you run a 64 bit os on a box with 1 GB of RAM anyway ?

[John Kline]

I only run 64 bit on my Raspberry Pi 4s because lots/most software is no longer sufficiently tested on 32bits.  Even is WeeWX is well tested on 32-bits, there is so much more that is running, and being updated, on the Pi.  As such, I would not push back on that IN MOST CASES.

But this is a case where you probably shouldn’t be running it.  I *think* the Pi Zero only has 512MB of RAM.  What all is running on the Pi Zero?  I expect it might be slow (there are plenty of reports of that), but I’m surprised there are crashes.

Could there be a temperature issue?

In the absence of the original poster sharing any logs, we're unlikely to be able to help.

Thank you for all the answers.
For information, the Pi Zero 2W is 64N with 512K of memory.
I used it in 64B version in lite version without screen.
I installed a cooler and its temperature is around 42°C on average. So there is no overheating.
Diagrams over several days show no overhead and no memory overflow. As a precaution, I modified the swap to 1024 instead of the original 256 but without any change!
Syslog and usersylog don't show anything special. Pi seems to completely crash and stop. No more SSH or HTTP connection and Weewx no longer records anything on the shutdown period.

Yes the Pi Zero 2W ONLY runs WeeWX.
I added some Python software for WEEWX skin complement and backup (USB SSD and cloud).

I am well aware that these crashes are not related to WEEWX which is written in Python.
Besides, I have already had problems with crashes when launching sudo apt update, for example. The Pi suddenly shut down with a fresh install, PiOS lite 64B and no software other than WeeWX and the Python libraries!
The purpose of my message was to know if others had tried WeeWX 24/24 7/7 in 64B on a Pi Zero 2W...

Thank-you...
