军哥，感谢百忙这中阅读此贴，服务器使用lnmp一直好好的，突然从今天开始就访问速度特别慢，还会出现
502 Bad Gateway，以前用着一直都好好的，突然就这样了，按常见问题中的解决方法修改了也不行，贴出日志，麻烦军哥帮助分析下：

看日期前半部分有程序长时间运行把php-fpm拖死了

张小凡 · 发表于 2013-6-7 16:39:20

首先感谢军哥百忙之中的回复，我继续贴出出现问题前到现在的日志，麻烦军哥分析下是什么程序把php拖死了？如何解决这个问题？我重启服务器N次了，依然不能解决，最坏打算，我现在用的是lnmp0.7 删除后安装1.0 是否可以解决此问题？请军哥明示，日志如下，大概是昨天晚上10点左右开始出现问题的

日志没法看出是哪个文件，必须用strace跟踪才行
升到1.0 应该还会一样

张小凡 · 发表于 2013-6-7 20:25:46

那个strace跟踪不会用，看了半天百度也没看懂，请问军哥，重装系统后重新安装lnmp 1.0 是否能解决问题呢？

licess · 发表于 2013-6-8 08:17:03

ps aux看占用高的php-fpm的pid
strace -o mystracelog.txt -p pid

这种问题重装不一定有效果

观测一会儿看看那个pid的大就跟踪那个，或先随便跟踪一个

如果你装的是论坛，先重启一下lnmp，TOP看一下mysql占用率。如果特别高。可能是cc攻击。

军哥求助，lnmp使用过程中突然不能用了，日志已贴出
