Unable to schedule

Hugging Face Spaces users reported a runtime error preventing deployments from starting, with spaces stuck in an 'APP_STARTING' state for 30-40 minutes before failing. The issue, which affected both new and existing spaces, was attributed to a resource shortage on Hugging Face's side and has since been resolved.

Unable to schedule

I deployed a space. It worked perfectly without any error two days ago. But today, when I logged in, the space was sleeping. When it woke up, it showed starting. After 30-40 mins, the space suddenly just showed this:

"runtime error

Scheduling failure: unable to schedule"

It happened with my other spaces which I created long ago. And the logs show:

β€œ===== Application Startup =====” I don’t know what is happening. Can anyone help me?

Same issue for me, it looks like a HF issue

Thanks for sharing. I thought I am the only one having this issue. I was worried since I have a competition tomorrow and need to present a live deployed version.

Perhaps due to a lack of resources, everything is back to normal now.

I also think the underlying cause was a lack of resources, but it seems to have been a real issue on HF side: Space stuck in APP_STARTING indefinitely - #6 by hysts
