RaspberryPi becoming unresponsive at random intervals (lemmy.world)

Issue Description: I have been having this issue with my raspberry pi running dietPi where it seems to lock up and I cannot SSH / access any of the services on it. The interesting part is that the interface seems to be up and I can still ping it on the local network but shows no video output. usually I get about 3-6 days before the issue appears again.

I am not really sure where to start to diagnose this issue. Any help would be appreciated!

Things Tried:

Reduced operating temp by getting a fan. I want to say this improved the length in between this issue appearing but don't really have any hard evidence.

uninstalled unused services

Limited active torrents in QbitTorrent

EDIT: Small thing to mention is that the CPU load is usually really high - like not uncommon for the load to be between 8-10 but I have seen it as high as 24.

Temporary fix:

Power cycle - everything comes up again in less than a minute.

Raspberry Pi 3B v2

OS: DietPi

Services:

Lidarr

Radarr

Sonarr

Prowlarr

Qbittorrent

Mullvad VPN - WireGaurd

@AverageGoob I have this issue with one of my hosts as well. It appears to be a problem with the micro SD card. Same card, different pi = same problem. I'm currently working around it with a watchdog but will need to replace the card soon.

Are you running your OS from USB or from a micro SD card?

I am running it from an SD card. Did setting up the watchdog ultimately work for you? I did come across a watchdog as a possible workaround.

@AverageGoob The watchdog saves me from rebooting the host manually, but at the risk of data loss (though not more than a locked up SD card). I configured a custom script that writes to a file, when the card has problems, the watchdog kicks in. To keep the script from stressing the card even more, the script only writes to the file every few minutes.
As you said it's only a workaround. I'll move the stuff on the problematic host to a VM with SSD shortly.
