最近阿帕奇一直在产卵，尽pipe似乎没有理由。 重新启动〜10分钟后，它会让产卵工作人员继续工作，直到达到最大数量，并且从不提供新的请求。
服务重启（ service apache2 restart ）后，我开始监视访问日志。 只有两个相当简单的要求，才开始产卵像疯子这样的工人：
#/var/log/apache2/access.log 66.249.64.215 - - [17/Feb/2016:00:30:18 +0000] "GET /wp-content/uploads/2015/08/colarinho_3.png HTTP/1.1" 304 179 "-" "Googlebot-Image/1.0" 201.80.103.196 - - [17/Feb/2016:00:33:00 +0000] "GET /wp-content/uploads/2015/09/circulo_cromatico.png HTTP/1.1" 200 40642 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0"
在完全停止提供新的请求之前，这是完整的状态。

它正在服务的网站有一个WordPress的安装。 我将其更新到最新版本并禁用了cron作业。 任何想法为什么发生这种情况或如何进一步debugging？
更奇怪的是：如果我做了一个lynx http://localhost/它会一直等待响应（即使Apache没有被工作超载），然后Apache立刻开始产生大量的工作，就像以前一样。
我用下面的conf使用mpm_prefork：
#/etc/apache2/mods-enabled/mpm_prefork.conf <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxRequestWorkers 50 MaxConnectionsPerChild 1000 </IfModule>
