php-fpm最近大量的创建和关闭进程的问题?

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

<code>[global]

error_log = /data/error/php-fpm.log-9002

log_level = error
events.mechanism = epoll
process.max = 4096
rlimit_files = 65535

[www]

listen = 127.0.0.1:9002

listen.backlog = 8192


pm = dynamic
pm.max_children = 256
pm.start_servers = 64
pm.min_spare_servers = 32
pm.max_spare_servers = 64
         
pm.max_requests = 10000

pm.status_path = /phpstatus 


access.format = "%R - %u %t \"%m %r%Q%q\" %s %f %{mili}d %{kilo}M %C%%"
    
slowlog = /data/error/$pool.log.slow-9002

request_slowlog_timeout = 2s 
    
request_terminate_timeout = 15s

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？

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。
