fastcgi php nginx 錯誤日誌搞砸了

我有一個奇怪的問題，我的 nginx 伺服器的錯誤日誌不知何故搞砸了：PHP 錯誤似乎都寫在一行中並遞歸地重複。這樣，llog 在一天內就增長了幾 GB！

這是錯誤日誌中的一行：

2020/03/26 16:58:45 [error] 29816#29816: *32 FastCGI sent in stderr: "PHP message: PHP Notice:  Undefined variable: SCRIPT_FILENAME in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 58PHP message: PHP Notice:  Undefined variable: pfad in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 60PHP message: PHP Notice:  Undefined offset: 1 in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 65PHP message: PHP Notice:  Undefined variable: benutzer in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 70PHP message: PHP Notice:  Undefined index: PATH_TRANSLATED in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 84PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice:  Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on li

這些行在 2048 個字元後被剪切。

在這裡，我在每個新錯誤之前拆分行：

這可能來自哪裡？如何在 nginx 中定義標準錯誤報告？

似乎帶有 fastcgi 的 nginx 捆綁了所有錯誤，這些錯誤發生在一行消息的一頁上。

如果腳本有很多錯誤（可能是由於 PHP 升級），那麼該行將被截斷為 2048 個字元。
