这张图片是fpm运行时进程数量。
机器上运行了两个fpm端口分别是9000、9002,运行的是不同的业务。
9000端口还基本稳定,但是9002看起来很不稳定!
php-fpm-9002.conf 配置

这个errlog的时间点其实和fpm进程起伏其实对应不上。
不知道是什么原因引起的,这种问题该如何去查?

<code>request_slowlog_timeout = 2s </code>
你可以尝试禁用这句话试试
这个是9002的php-fpm
pm = dynamic
pm.max_children = 256
pm.start_servers = 64
pm.min_spare_servers = 32
pm.max_spare_servers = 64
看一下9000的php-fpm配置是不是
pm=static

==========================================
观察一下cpu与内存的使用情况。应该是这方面的原因,开的进程太多,负载太高了。
