Hi,

 

now that I have Docker up and running, I am facing new problems.

After some time, the Zero stops working. I am connected with ssh, and the console is stuck.
The port 22 seems to be still opened for nmap, but I can't open a new ssh session anymore.

I was trying to monitor it with armbianmonitor -m, and I saw the processor throttling with the temperature rising.
Up to 62°C, it stays at 1200MHz, then it goes down to 960MHz, and I saw it once at 480 around 72°C.

As I thought that my problems were linked to the heat, I then used a fan and the temperatures stayed at max around 63°C and the CPU at 1200MHz.

But the problem still happens. After 7 minutes or so, the Zero stops working:

07:32:46: 1200MHz  4.86  78%  32%   0%   0%  45%   0%

As you can see in the logs, the load is heavy, but the temperature is low.
What could I check to know more about these crashes? Is there a message I could find in the logs after rebooting?

Is there anything I could use to know more about that? Is there anything I could do to prevent that?

Thanks.
