Having rebuilt discourse today, the CPU on my droplet is stuck at 100% and I am getting a 504 Gateway Time-out error. In terminal I have checked which processes are causing the issue and this is what I see: [Screenshot 2026-02-11 at 13.19.56] So it appears to be an issue with docker and a pitchfork command. Could someone help me understand what might be going on here and how I can address it. I have tried rebuilding the app again and restarting the droplet and still have the same issue.

How long have you waited on this state? We moved to a new webserver today, and sometimes it takes a little longer to fully boot.

Thanks. I didn’t realise that I could increase the memory on the droplet and then reverse it (as long as the disk size isn’t changed). I increased the memory temporarily to 8GB and everything started working as expected, with a CPU of 2-5% (see screenshot below), but when I reverted back to 2GB, which has always worked fine on a forum which only has very light use, the same issue returned with 100% CPU (see screenshot). How could I address this issue without permanently increasing the memory? [Screenshot 2026-02-11 at 14.20.40]

I’ve waited 30 minutes or more.

We’ve just merged a change that should fix the issue: https://github.com/discourse/discourse/commit/7324b327cdf72c2e468d33ce35074f5d1c78fe6f It should land in latest shortly, could you try updating your droplet when the fix is available?

Sure. When can I know when it’s ready?

You can check Commits · discourse/discourse · GitHub to see if the commit is in the list. Otherwise, I’ll let you know when I see it’s ready :slight_smile:

OK, thanks for letting me know.

Thanks. Everything’s working now with 2GB of memory.

Does upgrading your Droplet’s specs help?
