Orange Pi zero - freezing randomly

It is possible to hook a serial console to the board, but what kind of outcome do you expect?

 

If the kernel is trapping/crashing for some reason then this would likely be shown on the console, which could help provide a clue as to what might be going on...

I think it's a memory issue.

 

I have tested again with kernel 5.4.7 (Armbian 19.11.6)

I had a second ssh connection open this time running a "free -h" command every second.

While running apt on the first ssh connection it showed me that free swap went down to 0 bytes, used: 59 Mi, total: 59 Mi

 

I had changed zram config of armbian to use 25% instead of 50% memory. But I don't think that's the issue because others have the same problems without this change. And on kernel 4.19.x this memory issue does not seem to arise.

 

Also the fact that users with 512M memory don't have stability issues is a hint that it's a memory issue.

Setting CPU governor to performance (like described in this thread) does not seem to be a solution.

 

I had a freeze again while running apt and while CPU governor was set to performance running @ 1.01 GHz.

 

Memory before the test:

              total        used        free      shared  buff/cache   available
Mem:          238Mi        67Mi       132Mi       0.0Ki        38Mi       165Mi
Swap:          59Mi        20Mi        38Mi

 

Memory during the test (during freeze):

              total        used        free      shared  buff/cache   available
Mem:          238Mi        94Mi       127Mi          0B        16Mi       139Mi
Swap:          59Mi        58Mi       0.0Ki

Next run - this time with zram = 50%

 

After reboot:

 

              total        used        free      shared  buff/cache   available
Mem:          238Mi        72Mi       127Mi       0.0Ki        37Mi       159Mi
Swap:         119Mi       9.0Mi       109Mi

 

While "apt-get purge mosquitto" - it got stuck multiple times for a couple of minutes (=system unresponsive)

The whole process took waaaaay too long for just purging a package.

 

              total        used        free      shared  buff/cache   available
Mem:          238Mi        94Mi       122Mi       0.0Ki        20Mi       137Mi
Swap:         119Mi        79Mi        39Mi

@5kft You could try to do some apt-get install commands.

For example: apt-get install php7.3-fpm, apt-get install mosquitto

Then purge again.

 

And look if your swap gets used...

Maybe this is only orange pi zero specific. But it is 99.99% NOT a hardware issue. It must be a software issue. Something in the kernel, or a driver is eating up memory or the swap usage isn't configured correctly.

Did an "apt-get install mosquitto" and while "Setting up mosquitto" it said "Killed"

 

Dmesg gives me:

I changed the swappiness from 100 (=aggressive swapping) to 20.

sysctl -w vm.swappiness=20

 

System seemed more responsive first but it got stuck again when installing php7.3

 

I set up the led to blink when accessing the sd card:

echo "mmc0" > /sys/class/leds/orangepi\:red\:status/trigger

 

It's fully on now.  System only responds to pings. Guess the system is so busy that it doesn't even switch the LED.

governor for all 4 cpus:
 

  driver: cpufreq-dt
  CPUs which run at the same hardware frequency: 0 1 2 3
  CPUs which need to have their frequency coordinated by software: 0 1 2 3
  maximum transition latency: 5.44 ms.
  hardware limits: 480 MHz - 1.01 GHz
  available frequency steps: 480 MHz, 648 MHz, 816 MHz, 960 MHz, 1.01 GHz
  available cpufreq governors: conservative, ondemand, userspace, powersave, performance, schedutil
  current policy: frequency should be within 480 MHz and 1.01 GHz.
                  The governor "ondemand" may decide which speed to use

Next memory exception (page allocation failure) I found while doing rsync...

This time I even disabled ram-log (50MB). ZRAM still @ 50%.

During this failure the system did not freeze. So even if you have 512M, there might still be something broken with page allocation on kernels after 4.9.x!
