对不起，如果这似乎漫步。 我一直试图解决/解决这个过去20个小时的直接，而不得不保姆服务器，并重新启动php5-fpm每次下降。
我想象一个插件（高stream量的WordPress站点）或挂在那个线程，可能会导致绑定其他线程的依赖锁的一个基本问题。 我的直接担忧是find方法来使emergency_restart_threshold在需要时自动重启php5-fpm。 然后我可以睡觉，并find潜在的PHP问题。 这个问题在过去24小时里发生了21次。 有时甚至相隔3.5小时，其他时间只有几分钟。
我已经尝试过不同的时间值，但到目前为止似乎没有触发所需的SIGSEGV或SIGBUS信号。 看起来问题一旦出现，所有的PHP请求都会挂起，就好像它们都在等待什么东西一样，150个最大的孩子最终会在各种超时closures之前填满传入的请求。 除了这个问题发生的时候，通常只有2-5个孩子需要满足现在的交通。
服务器是运行Ubuntu 14.04的Amazon EC2 c4.Xlarge（7.3 Gb RAM，4 vCPU）。
我也安装了New Relic，资源看起来非常好。 超过一半的内存可用，CPU使用率通常远低于50％，除了PHP5-FPM挂起之后。
