ローカルで動作している間に、このPUTリクエストがGoogleコンテナエンジンの予期しないEOFで失敗する理由を教えてください。

Question

EDIT：追加ステータスコードは、クライアント

EDIT 2で受信された：問題は本質的にランダムであるように思わ、それが発生したときに、それが唯一の時間に特定のネットワークに影響を与えているようです。最近、別の国のチームメンバーが問題に直面し、同時に自分のネットワークから問題なく働いています。以前は私のネットワーク上でこの問題に直面していましたが、クラッシュサーバーにssh接続した後、同じ呼び出しをカールで実行することができました。

EDIT 3：問題はあまりにも

私はGoogleのコンテナEngine上に配置されたときに奇妙な問題を与えている春のブートベースのREST APIの実装を持つPUT以外の要求に起こっています。問題の重要ポイント：

1. 埋め込み型のTomcatではローカルで問題なく動作します。
2. コンテナエンジンでは、この問題はHttp PUTリクエストでのみ発生しています。方法をPATCHに変更すると、エラーが消えてしまいます。
3. 私は同じスタックを持つ別のアプリケーションを数か月にわたってコンテナエンジンにデプロイしましたが、そのアプリケーションではこの問題に直面しませんでした。
4. クライアントでは少し遅れて504 Gateway Timeoutが届きました。これは、ウェブサーバーが依然としてリクエストが到着するのを待っている間に、ロードバランスがウェブサーバーの応答を待っていることを示唆しています。

私はGKEの負荷分散/ネットワーク層のバグに遭っていると思われます。続い

Answer 1

PUT HTTPリクエストは、典型的には、PATCH HTTPリクエストリソースの典型的な更新部一方、全体のリソースを更新します。その意味は、一方が他方よりもオーバーヘッドが大きいことです。私は前に504sを見て、その根本的な原因は、タイムアウトバックエンドサーバーに接続していた。したがって、PUTリクエストが完了するまでに時間がかかりすぎる場合は、タイムアウトが発生する可能性があります。あなたのPATCHリクエストは仕事が少なく時間切れではないので、おそらくもっと早く完了します。可能であれば、バックエンドサーバーのタイムアウトを増やしてください。
