我尝试过各种各样的选择,但是每隔几天(大多数时候每天)FPM停止提供页面,我得到502(来自切诺基网络服务器)
原文链接：https://www.f2er.com/php/139304.html日志中包含以下内容：

每次发生这种情况时,最后一次记录都类似于
[15-Sep-2014 11:01:34] WARNING: [pool www] server reached max_children setting (50),consider raising it
这是切诺基同时的连接,它甚至不是尖峰……
我尝试过动态,固定的按需,没有任何变化.无论我设置什么max_children它最终都会死掉.
为什么它不能恢复我不知道,但现在要切换到其他东西或制作一个每30分钟重启FPM的crontab
