Apache - 负载/带宽非常高，请求模式异常

我是一名 Web 开发人员，有一台服务器，用作某种开发机器。因此，我使用 Apache 的经验是，我可以随意摆弄并完成基本工作/使用 Google 搜索来获得我需要的答案。

周末，我们的服务器负载非常大，大约是平均带宽使用量的 1000 倍。我的 Apache 访问日志中有几行类似于下面的内容。

同一组图像被反复请求我自己的服务器！另外，用户代理只是一个破折号。

  • 一旦我重新启动服务器，文件下载就会再次开始。
  • 我在访问日志中发现了几行/feed由用户代理请求的 内容"-" "Apple-PubSub/65.28"。我检查了用户代理，这似乎是有人要求他们的 Mac OS 管理他们的订阅源。
  • 该网站使用 WordPress 构建。但是，没有安装任何插件等。
  • 我正在使用函数getimagesize和库 timthumb (Php)。这些函数和库是否会导致这些问题？
