Hello,
I just setup an application on a Raspberry Pi 4 in a passively cooled case and it appears to be freezing on a daily basis. I guess this could be power, temperature, or software. Where do I start to troubleshoot it?
Thanks,
A.
Hi there,
Firstly you’ll have better luck debugging if you enable persistent logging (available in the Device configuration panel).
Second, I always recommend taking a look at the diagnostics, specifically the checks.
Finally, take a look at our device debugging masterclass (https://www.balena.io/docs/learn/more/masterclasses/device-debugging/) for further ideas. If you get stuck, feel free to ask and we’ll be able to provide a bit more guidance based on what you observe.

Thanks, I have enabled persistent logging.
At the moment, everything looks pretty normal:
Device health checks are all green.
So now I wait…

Hi there,
I see you are using a raspberry Pi 4. Raspberry Pi 4’s require more power than most USB adapters can give, so I am wondering if you are not powering it with enough power. The raspberry Pi 4 requires 5 volts at 3 amps. For more information, see the raspberry Pi documentation https://www.raspberrypi.org/documentation/hardware/raspberrypi/power/README.md

Thanks @Plefunga, that’s a good thing to check. I checked the power supply and it is rated for 3A, but has no brand. So I just switched it to the unit that came with the Argon NEO case, which is branded “Argon” and is rated for 3.5A. I must have grabbed the wrong one out of my junk drawer…
Meanwhile, it hasn’t crashed since I enabled persistent logging.

Seems the power supply was indeed the cause.
