php-fpm总是宕机

[卡卡吉利]

Nginx+php5-fpm,部署的一个开源的项目,已经几个月了,从来没出问题,最近一周总是出现无法访问的情况,重启fpm就好了,不太会看日志,谁能帮我看看是什么问题:

你这是进程不够用，适当增大你的 pm.max_children

[xuzuning]

表面上看是 并发数不够，实际是内存不够用 你最近又添加了什么服务类软件？

我增大了,但是重启后访问很慢.系统负载蔡零点几

系统负载才零点几,个位数并发,8G内存.自从部署上就没有改过,机器是独立的,没有别的服务

8G内存，试试这个配置

pm = dynamic
pm.max_children = 200
pm.start_servers = 100
pm.min_spare_servers = 30
pm.max_spare_servers = 200
pm.max_requests = 1000
