Originally, I didn't want to write this, but it was supposed to be a problem of operation and maintenance, but it was found that such a problem had occurred recently. Some machines were configured with net.ipv4.tcp_tw_recycle=1, which means to enable the rapid recovery of TIME-WAIT sockets in TCP connections.

This configuration can lead to a problem, when the service is a gateway class application and the traffic is high, it is easy to have a lot of connection rejections.

In the linux 4. 1 kernel, the net.ipv4.tcp_tw_recycle parameter is removed.
