    Schroedingers Cat got a reaction from aegiap in Armbian 20.11.1 Focal Freezes?   
    Support told me to do the following:
     
    Run `armbian-config`, go to -> System -> CPU
     
    And set:
    Minimum CPU speed = 1200000
    Maximum CPU speed = 1200000
    CPU governor = performance
     
    I'm now writing to my HDD via SFTP for more than 1.5 days without an issue, so that seemed to solve it.

    Schroedingers Cat reacted to Carlos Hartmann in Semi-regular crashes and reboots   
    Setup: Helios64 with Armbian 20.08.8 Buster with Linux 4.4.213-rk3399. Will change to Linux 5.8 soon though. 5 x 8 TB drives. Not using battery.
     
    I’ve had this issue ever since beginning to use my Helios. It first happened when I tried building a RAID with OpenMediaVault: It would crash and reboot while building. Sometimes after only 10 minutes, sometimes after 8+ hours of working. The same is true for video transcoding nowadays: it will sometimes crash after a little while, sometimes after a few consecutive hours of working, but it will never be able to work much longer than 12 hours on such a task. Copying large files from the internet has a similar risk of crashing it.
     
    Also, it will not save the crash in the logs. For some reason, the timeframe when it crashed was always gone from the logs. Nowadays it’s even worse: My logs only go until December 11th and even if I clear them on the OMV interface, after the next reboot, they are there again and it refuses to log anything new.
     
    While the server is performing a demanding task, most figures in the ssh screen will be red: System Load at around 170%, CPU temp at 70°C etc. CPU usage on the OMV interface will be around 97%.
     
    At first I thought it was normal but a friend of mine told me servers should absolutely never reboot on their own; that this is an indication something is not right.
     
    My impression from the above-described behavior is that somehow my machine isn’t able to limit the amount of CPU used. I expected the server to become slower under more CPU stress, but instead it seems to not regulate well at all and overwork itself. Or maybe some part of the software/hardware is faulty and will randomly cause a crash.
     
    As you may have noticed, I’m rather new to a lot of things here. I have no idea how to even begin troubleshooting this so I’ll need some pointers from you. What could be the cause for this and what tests can I do to narrow it down?

    Thanks for your response. I'm only allowed to answer after 24 hours, for some reason.
     
    I disabled the log2ram but the log files are still not showing anything interesting. Crash happened on 15th of December around 16:00 and restart was around 19:50.
    Here's the relevant section from /var/log/syslog:
     
    /var/log/kern.log:
     
    Nothing interesting found in /var/log/dmesg.
     
    Do you mean connecting via COM/USB? I lose connection if it happens, but I can try.
     
     
    Anything else I can do to investigate this? Do you think my device is broken?

    I'm using Armbian 20.11.1 Focal (5.9.11-rockchip64) on my Helios64. When there's heavier load via ethernet (SFTP to a SATA Ultrastar 12TB disk) for something like more than an hour, the entire system will freeze. Not sure if it actually does freeze but I lose all SSH connections and cannot connect anymore via SSH unless I restart the Helios64. Happened today 4 times and it's totally reproducible. Haven't tested another drive yet.
     
    What makes this difficult to debug is that under /var/log/syslog or kern.log or faillog nothing relevant is being written as to in what state the device is.
     
    Is this a known issue?
    How can I find out what the problem is?
