我正在運行一個帶有apache 2.4和php 7的debian服務器。* 每天有1 - 3次我的網站出現故障，我必須重新啓動apache才能重新啓動它。apache2每天不斷崩潰1-3次
我是相當新的Linux，所以我真的不知道如何調試Apache：/
任何意見強烈appriciated！

有什麼事我可以張貼到幫助查找問題？
====================！=！=！=====================
我可能已經找到了問題
注意到在錯誤日誌中一個新的錯誤說：
server reached MaxRequestWorkers setting
然後，我開始googleing與本網站受傷了：
http://cloudinservice.com/tune-apache-performance-using-mpm-prefork-module/ 那對我發生的事情給了我一些祕密mpm-prefork-module
然後我注意到MaxConnectionsPerChild其中設置爲0，這意味着如果我有一些PHP腳本有一點內存泄漏，將繼續增長和吃掉更多的內存不釋放任何隨着時間的推移這解釋了爲什麼服務器突然崩潰，我根據自己的資源修改了文件並重新啓動了apache。
我會在接下來的幾天看到它是如何發展的，如果它發生崩潰，我會返回併發布這個答案。
