池信号15退出（SIGTERM）：执行超时

我在1GB的单核VPS上运行Nginx 1.5.1和PHP-FPM（PHP 5.3.26）的Drupal 6，SSD存储上有3GB的交换空间。 我刚刚从共享主机切换到这个非托pipe的VPS，因为我的网站变得太重了，所以我仍然在学习绳索。 我有很高的stream量，我没有真正注意到，但谷歌Adsense通常每天接近3万页的浏览量。 我通常有50到80个经过身份validation的用户login，另外还有几百个匿名用户在任何特定时间点击Boost静态HTMLcaching。 我最多configuration了10个PHP-FPMsubprocess。 我正在使用“ondemand”PHP-FPM进程pipe理器。

我偶尔遇到一个很难debugging的错误，因为它看起来是随机的。 用户可能有30多个故意的post，其中1个被复制。 我configuration了它，所以后button被禁用后，第一次点击，所以这不是双击的结果。 实际上，当我发布的时候，它甚至发生在我身上。 双职位发生在几秒钟内。 我检查了日志文件，并且重复的post似乎总是对应于nginx的POST错误： recv() failed (104: Connection reset by peer) while reading response header from upstream 。 而这个事件似乎涉及index.php和PHP-FPM工作进程的后续SIGTERM执行超时错误的PHP-FPM错误。

以下是nginx访问和错误日​​志以及PHP-FPM错误日志：

他们被修剪和稍微混淆，以显示一个重复的post错误，发生在今天12:34我的IP地址为“1.2.3.4”。 发生该事件的节点是22802。

当我在我以前的共享虚拟主机上运行Apache / FastCGI时，没有发生这个问题。 我还应该提到，我正在使用Redis进行caching，并使用Zend Optimizer + opcache。 但我试图禁用这两种机制，以避免愚蠢的错误，没有任何区别。

感谢您的任何帮助，您可以提供！
