fpm_children_bury 网站前台访问正常，后台严重迟缓

yanqzh

云主机以前放的是杰奇小说系统的网站，十分快速且正常，其后关闭并迁入discuzx3.1打造的论坛，结果非常奇迹，前台从未出现过502badgateway，但后台打开插件，或执行某些功能时，出现严重迟缓：


vi /usr/local/php/logs/php-fpm.log 得以下warning（日志末尾部分）:

1. Apr 05 23:16:41.117876 [WARNING] fpm_children_bury(), line 215: child 7399 (pool default) exited on signal 15 SIGTERM after 50.294062 seconds from startApr 05 23:16:41.117903 [WARNING] fpm_children_bury(), line 215: child 7400 (pool default) exited on signal 15 SIGTERM after 50.293782 seconds from startApr 05 23:16:41.117912 [NOTICE] fpm_pctl_exit(), line 81: exiting, bye-bye!

复制代码

查看探针p.php发现，内存使用率非常高：



参考了网络文章：不见效，以下为其一：
file:///C:\Users\yan\AppData\Local\Temp\%W@GJ$ACOF(TYDYECOKVDYB.pnghttp://www.kuqin.com/web/20120220/318312.html


执行netstat -anpo | grep "php-cgi" | wc -l
发现值为7


php-fpm设置apche-like，max-children=70 ，  maxspareservers=60  ，内存2G，这样设置是否有问题？

日志上看是怎么回事？

licess

看上面有fsockopen可能是dzx后台调用外站的扩展那些东西的很慢造成的

yanqzh

貌似调用的是数据库，目前是5.1的，能直接升级到5.3吗？

yanqzh

之前确实有过数据库无法启动的错误，後来修复数据表，就能启动了。但是後台莫名其妙的慢

licess

可以升级，只要程序上支持5.3就行
