网络错误的解决方案（tcp_error）

Question

我在其中一个页面上收到以下错误：

Network Error (tcp_error) 

A communication error occurred: "Operation timed out"
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

For assistance, contact your network support team.

我在这里找到了一些关于这个问题的答案：

作为网络管理员，有什么办法可以防止这种情况发生吗？也许更改apache配置？我认为这个错误发生在客户端是否正确？
