misskey プロフィールの変更をすると負荷が異常に上昇する

💡 Summary

バグなのかは不明です...

プロフィールを変更(i/updateを叩く？)すると、MisskeyプロセスのCPU使用率が増加します。 Redisは正常だと35MB程度プロフィールを変更したタイミングで100MB程度になります。 MisskeyのmasterプロセスのCPU使用率が60%程度になります。

同時にこの現象が終わるまで127.0.0.1に10MiB/s程度の通信(送信)をします。

また、同じマシンでオンラインユーザーが自分一人だと同等の現象は確認できませんでした。

下記に書かれているバージョンはForkとなっていますが、バニラのMisskeyでも同じような事が起きることを確認しました。

🥰 Expected Behavior

正常時のまま動き続ける

🤬 Actual Behavior

異常なほど動作が重たくなり、 Gateway Timeout が出たり Bad Gatewayが出たりする

📝 Steps to Reproduce

プロフィールを変更する
重たくなる

i/updateはプロフィールの情報以外もミュートワードなど色々と送っているようなので、リクエストのボディなどペイロードを記載するとデバッグの助けになるかも知れません。

ざっと該当のエンドポイントのコード見た所管

https://github.com/misskey-dev/misskey/blob/f6af6d9679305b36dc993a310462a6065248ae1a/packages/backend/src/server/api/endpoints/i/update.ts

変更がある場所をクライアントが判断したりとかせず、全部送ってそれを基に全部の値を上書きするような処理になってて一回送ったペイロードからオブジェクトに一個一個値を代入していくようなコードになってるからこのエンドポイントの負荷が高いかもしれない

CPUProfileとHeapSnapshot上げておきます参考になれば幸いです HeapSnapshot(GoogleDrive) cpuprofile

件のメモリリークと関連がある可能性もあるのでそれが終わってからも続くかを様子見したさはある

May 21 '24 14:05 tai-cha

2024.5.0-beta1のため

May 21 '24 14:05 tai-cha

すみませんこれhappy-domをJSDOMに置き換えてます

May 21 '24 14:05 mattyatea

なるほど、となるとこのエンドポイント自体が重い可能性が高い可能性はあるわね

ちょっと前の話なので参考までプロフィールのリンク検証をコメントアウトするとMisskeyが落ちなくなったり、メモリ使用量が減ったりしました。 (何かの規則に合致するリンクだとMisskeyとnginx用サーバーのあいだでclose_waitが大量に発生してた)

try-catchを挟んでwindow.close()を発火するようにしたら変わる？
