How should we know? You've got the two applications, you know what they're trying to do. From the log it seems that you either have serious network issues, or you're dealing with an attack of some kind - RST just means "I'm totally confused, let's try all over again".

If you look carefully, then you'll notice that there has been several issues with the connection which include.
1. TCP duplicate ACK
2. TCP out of order
3. TCP retransmission
These might lead to something which shows that the connection has some issues.

client can send the data to server at frist, The network latency might be one of the reasons, when I send the data to the port, the port is already closed, so I receive RST.
