目前我们的BBS跑在这台结构上,在每天早上八点并发非常高,达到五百多,平时也就几十个并发!

基本要一个小时就降下来了.


在Nginx 日志中发现很多 http 1.0 499 的错误!

在php fpm日志中:

没人遇到过这个问题吗?现在又出现这个问题了,每天早上都会有一个小时,这三天以来!

晕，我也遇到一样的问题，环境基本相同，也是Nginx + PHP FastCGI，这两天早上总有一段时间狂报499错误，用
netstat -anpo | grep "php-cgi" | wc -l

查看使用紧的进程数，居然比平常多出2~3倍，CPU几乎耗尽，也是大概1个小时后就变回正常，不知何因。。。

我的也是这个问题，当时看到网上有说是配置文件和启动文件不一致导致的，可没发现我的配置哪里有不一致的

如果前端没有问题,请详细分析一下后端是否有问题
