我有我的apache服务器configuration工人MPM如下：
<IfModule mpm_worker_module> ServerLimit 20 ThreadLimit 50 StartServers 3 MaxClients 1000 MinSpareThreads 50 MaxSpareThreads 200 ThreadsPerChild 50 MaxRequestsPerChild 10000 </IfModule> 该服务器每天需要约200万个请求。 当请求到来时，Apache服务器将停止接受新的连接（浏览器无法连接）。 这个过程将保留在过程列表中。 内存使用率约为10％，CPU为0％。 看来apache服务器无法在应该的时候回收这些进程。
我发现与错误日志中的崩溃相关的东西：

有任何想法吗？ 谢谢！
你可能想用mod_status来检查你的服务器状态。 您可能有不断线的连接，并处于“发送应答”状态（W）。 看看这篇关于如何诊断这个解决httpd maxclients和modstatus报告的文章
