Hi all — having trouble with high CPU on “ backend “ container

  • OS: Linux 6.1.0-38-amd64 Debian 6.1.147-1 x86_64 GNU/Linux

  • Container runtime: Docker

  • Service: backend ( image: penpotapp/backend:latest)

  • Deployed: ( docker-compose )

  • Observed very high CPU usage in docker stats: about 300% for the backend container

  • Issue started: after deploy

  • CPU does not returns to normal for ~5 minutes , i waited for ~5 minutes and then stop it.

Appreciate any help — I can attach logs and more info on request.

Fixed — reinstalling Penpot with the official docker-compose file solved the high CPU issue. After redeploy the backend container’s CPU dropped back to normal.

Looks like my custom compose caused the problem.
