Hello, I have a Dockerfile where I have configured a supervisor for workers, but after deploying the application my workers did not start taking tasks from SQS. I already checked the runtime logs section and this log keeps repeating Unlinking stale socket /var/run/supervisor.sock. I did check var/run directory and there no one supervisor.sock file only supervisor.sock.9. I don’t know how to fix it, everything was working fine yesterday. I didn’t make any changes to my “Dockerfile”. I would appreciate your help, thank you.

Hi there,
Would you mind sharing your Dockerfile here if possible so I could take a quick look and see if I can identify what might be causing the problem.
One thing that you could try out is to add a command in your Dockerfile to remove the stale socket before starting the supervisor:
RUN rm -f /var/run/supervisor.sock
CMD ["supervisord", "-c", "/etc/supervisor/conf.d/supervisord.conf"]
That way the stale socket file is removed each time the container starts, preventing the error from occurring.
Best,
Bobby
I’m having the same problem. Our deployments to app platform stopped working on the April 8. maintenance deployment. A deployment about four hours before the maintenance deployment was deployed without a hitch.
Now I’m getting the Unlinking stale socket /var/run/supervisor.sock message during deployment until it times out.
Had the same issue, but my builds started working again randomly last night. I guess something was fixed as I haven’t made any changes.
EDIT: No never mind, it still doesn’t work.
