我有这在我的Apache服务器状态消息：
LLLLLLLLLLLLLLLWLLLLLLLLWLLLLLWLLLLLLLLLLWLLLLLLLWLLLLLLLLLLLLLL WLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLWLWLLLLLLLLL LLLLLLLLLLLLLLLLLLWLLLLLLLLLLLLLLLLLLLLRLLWLLLLLLLLLLLLLLLLLLLLL LLLLLLLWLLLWLWLLLLLLLLLLLLLLLLWLLLLLLLLLLLLLLLLLWLLLLLLLLLLLLLLL LLLLWRLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL LWLLLLLLLLWLLLLLWLLLLLLLLLLLLLLLLLLLLLWLLLLLLLLLLLLLLLLLLLLLLLLL LLLLLLLLLLLLLLLLLLLWLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLWLWL LLLWLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLWLLLLLLLLLWLL
可能是什么原因？ 所有512个插槽都被填满，每秒请求数只有3. CPU负载达到250+（15米）。 它是一种DDOS？ 因为很多请求都只是GET请求，使许多具有不同IP地址的不同虚拟主机很多。
这意味着apachelogging一个请求的时间要比接收，处理和发送响应的时间要长得多。 这似乎不大可能。 您的文件系统出现问题的可能性更大。
（如果您提供了服务器状态的完整输出，这将会很有帮助）
下一步是在系统日志上logging日志 – 查看硬件是否有问题。 如果还在发生，请检查iotop的输出。 如果这些显示没有任何错误，然后看看你的networking服务器日志（访问和错误）。
这可能只是因为你没有把日志轮转太久。
