[orange PI PC freeze > 80+ temps, EPOCH =~ 1 year]

 

I have a similar problem, my orange does not freeze, but the script that is running in the background freezes or stops working

[Orange Pi zero - freezing randomly]

 

I am suffering from the same problem, but my orange freezes only the script that is running in the background, the operating system remains running without a problem. already managed to solve your problem?

[Problem with script on background]

 

I have a problem with a script python that is running in the background, this script needs to run all the time without stopping, but the script freezes or stops without error,  when I change for another card, it works for a few days and then the same thing happens, however the debian system continues to work perfectly, only the background script stops working, I already debugged the code and it has no problem making it stop. my sdcard is MicroDrive class 10, 8Gb. what could be causing this problem?

[Random Reboot on my orange pi zero]

im working on an embedded system, but i have a problem with random reboot, my orange pi zero, works well but sometimes it restarts for no apparent reason,  

it's not a problem with my script because it happens even without the script working,  problem can it be my sd card or power suply, or something?
