请大神帮忙看看这到底咋回事，预缓存问题。

gamer

不能不说lnmp环境性能的确出众，我是从wdcp转到lnmp的，一用就舍不得丢了。
不过有个问题 就是预缓存。我用的是wordpress 插件wp-super-cache的预缓存功能。

环境：之前在Linode vps  CentOS 6.5 64位 wdcp环境， wordpress  插件wp-super-cache的预缓存功能一切正常。
           现在转到阿里云ecs CentOS 6.5 64位 军哥lnmp一键包环境，其它都正常 就wp-super-cache的预缓存不正常。
现象： 比如指定120分钟预缓存一次网站全部内容，时间到了后缓存页面开始工作。问题来了，只缓存几十个页面后自动停止了，一直显示定在那里不缓存了。只有等下一次的120分钟到来，又开始接着上次的id缓存剩下的页面，又缓存几十个页面又停止了。

请问这是这么回事，是不是lnmp环境里 哪里的设置需要修改？？

不清楚具体原因，你php是什么版本

开慢日志和php错误日志看看

gamer

现在用的 php 4.4.40  以前用的是5.3的

错误日志 好像就一个 nginx_error.log 25日的

2016/02/25 14:21:29 [crit] 13105#0: *1616 connect() to unix:/tmp/php-cgi.sock failed (2: No such file or directory) while connecting to upstream, client: 60.210.10.50, server: www.yydxh.net, request: "HEAD / HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-cgi.sock:", host: "www.yydxh.net"

licess

这个不是php-fpm的错误日志，这是nginx日志，只是说了php-fpm可能挂掉了

pm.max_children = 10
是不是跟这个子进程数量有关？设小了？？

licess

上面日志只有wp-cron执行超时的信息，可以增加超时时间或设为0不限制试试，置顶帖502排查解决方法里有具体修改方法

谢了 军哥

我试试
