@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’d bet $1 it’s the SD card. My 3B+ used to have the same problem. Been running pis off some sort of SSD ever since, no issues.
Pi 3B has dedicated bus for SD card but ethernet and usb share bandwidth. Enable zram, disable all swap and keep using sd card.
@a_fancy_kiwi I agree, same here. This is the last pi that's running off an SD card with services that do "significant" disk I/O. I have a few zeros that only really write to the card for OS updates. Their job is to collect data and send it via the network. I haven't had issues with that kind of workload using micro SD cards.
Edit: For Pis with write workloads I'm using basic USB3 SSDs. Didn't have good results with USB sticks though.
Id be willing to try this. How do you have it connected? Just using an external USB attached one?
I upgraded to the Pi4 but I use this case. It has a daughter board that lets me use an m.2 SATA SSD over USB. But any USB to SATA adapter should work fine
You should get a scsi enabled adapter though, otherwise you may have to disable it in the kernel boot settings. And if you forget that it will run at like kbit/s.
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.
