セルフホストランナーで正常に稼働し続けていた GitHub Action が突然 stuck するようになった

GitHub の Incident だった

ビルドやテストは正常に完了してそうだが、最後に以下のログを出力したまま普段1~3分で完了するアクションが30分以上待っても終了しない

Cleaning up orphan processes

表示上の不具合で、他のPRを作成し、別のActionが実行されれば問題無くなるか確認するも、同様の状況に

セルフホストランナー上では正常にプロセスが開始して終了してそう

ActionのCachesを全て削除してもダメ

Cancel workflowボタンをクリックしてみる

「You have successfully requested the workflow to be canceled.」というメッセージは表示されるが、workflowは停止しない
