php-fpm最近大量的建立和關閉進程的問題?

這張圖片是fpm運行時進程數量。
機器上運行了兩個fpm連接埠分別是9000、9002，啟動並執行是不同的業務。
9000連接埠還基本穩定，但是9002看起來很不穩定！

php-fpm-9002.conf 配置

fpm error log

這個errlog的時間點其實和fpm進程起伏其實對應不上。

不知道是什麼原因引起的，這種問題該如何去查？

request_slowlog_timeout = 2s 

你可以嘗試禁用這句話試試

這個是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

==========================================
觀察一下cpu與記憶體的使用方式。應該是這方面的原因，開的進程太多，負載太高了。
