我有一個 AWS Lightsail 實例，並在不同連接埠上執行 NGINX 和 apache。 （Apache 在 8080 上，Nginx 在 80 上）。它運作良好，但從早上開始，Nginx 停止工作，重新啟動時出現以下問題。我的任何網站都無法加載

這是nginx的錯誤日誌
2020/08/26 06:17:09 [alert] 1930#1930: *20 open socket #18 left in connection 9
2020/08/26 06:17:09 [alert] 1930#1930: *35 open socket #17 left in connection 14

我已經嘗試過 nginx -t 。這也是成功的。
請幫忙解決這個問題
