You shouldn’t use Tor for torrents https://blog.torproject.org/bittorrent-over-tor-isnt-good-idea/

It just happened again. I couldn’t ssh in despite the limit on docker resources, which leads me to believe it may not be related to docker or Lemmy.

This time it lasted only 20 minutes or so. Once it was over I could log back in and investigate a little. There isn’t much to see. lemmy-ui was killed sometime during the event

I still have no idea what’s going on.

I had the same thing happen. Max CPU usage, couldn’t even ssh in to fix it and had to reboot from aws console. Logs don’t show anything unusual apart from postgres restarting 30 minutes into the spike, possibly from being killed by the system.

You say yours solved itself in 10 minutes, mine didn’t seem to stop after 2 hours, so I reeboted. It could be that my vps is just 1 CPU, 1 GB RAM, so it took longer doing whatever it was doing.

Now I set up RAM and CPU limits following this question, and an alert so I can hopefully ssh in and figure out what’s happening when it’s happening.

Any suggestions on what I should be looking at if I manage to get into the system?

I figured it out after a good night’s sleep.

The UI doesn’t let you send a request with empty allowed instances, it either sends an array with your picks or no array at all if you selected none. To reset allowed instances you need to send an empty array to the API.

The easiest way to do it is

• Open browser devtools network tab or equivalent
• Send a request with at least one allowed instance
• Edit the request JSON body to empty the array
• Resend the request

I think Chrome lets you copy the request with authentication to send with something like curl, I used Firefox which lets you edit and resend directly.

Peace ✌
