次のコンポーネントを備えたサーバーがあります。
- Ubuntu 12.04
- ニンクス 1.2.2
- 乗客 3.0.15
このサーバーで Ruby on Rails アプリを実行しています。現在、Nginx の error.log で、このエラーが定期的にポップアップしていることがわかりました。
[ pid=12615 thr=3065355072 file=ext/nginx/HelperAgent.cpp:923 time=2012-10-22 09:31:03.929 ]: Couldn't forward the HTTP response back to the HTTP client: It seems the user clicked on the 'Stop' button in his browser.
この問題がどこから来たのか誰にも分かりませんか? これは私のNginx confです:
