The issue appears to be a scheduling or capacity shortage on Hugging Face's side, as restarts, factory rebuilds, and hardware toggles fail to resolve it. Some users eventually see a 'Scheduling failure: unable to schedule' runtime error.", "body_md": "[Winou](https://discuss.huggingface.co/u/Winou)\n1\nMy Docker Space (free cpu-basic) has been stuck in `APP_STARTING`\n\nfor over an hour and won’t come up.\n\n**What I’m seeing:**\n\nThe API reports `stage: APP_STARTING`\n\nwith `hardware.current: null`\n\nwhile `hardware.requested: cpu-basic`\n\n. So no machine is actually being allocated.\n\nIn the Hardware settings, the “CPU basic” card shows a spinner as if it’s continuously searching for resources.\n\nThe public endpoint times out (HTTP 000).\n\nWhen it *did* briefly start earlier, the container logs were completely clean — the app bound correctly to `0.0.0.0:7860`\n\nand logged `Server listening`\n\n, but the UI never transitioned to `Running`\n\n.\n\n**What I’ve already tried (none worked):**\n\nRestart (rebuilds in ~0.5s from cache, then straight to “starting”, nothing happens)\n\nFactory rebuild (full rebuild completes, still stuck)\n\nToggling hardware / re-selecting CPU basic\n\nThis looks like a scheduling / hardware-capacity issue on HF’s side rather than my app. Is there a current capacity shortage on the free cpu-basic pool? How long does this usually take to resolve, and is there anything I can do besides waiting?\n\nThanks!\n\nI have some news, my space just did runtime error\n\nScheduling failure: unable to schedule\n\nContainer logs:\n\n===== Application Startup =====\n\nSame issue for me, it looks like a HF issue for me", "url": "https://wpnews.pro/news/space-stuck-in-app-starting-indefinitely", "canonical_source": "https://discuss.huggingface.co/t/space-stuck-in-app-starting-indefinitely/177564#post_2", "published_at": "2026-07-08 10:42:00+00:00", "updated_at": "2026-07-08 11:13:16.878117+00:00", "lang": "en", "topics": ["ai-infrastructure"], "entities": ["Hugging Face", "Docker Space", "CPU-basic"], "alternates": {"html": "https://wpnews.pro/news/space-stuck-in-app-starting-indefinitely", "markdown": "https://wpnews.pro/news/space-stuck-in-app-starting-indefinitely.md", "text": "https://wpnews.pro/news/space-stuck-in-app-starting-indefinitely.txt", "jsonld": "https://wpnews.pro/news/space-stuck-in-app-starting-indefinitely.jsonld"}}
