Hi all

The wireshark capture seen in the screenshot below is between linux server and charging system, although the operation always succeed; but as you can see there are a lot of Retransmissions [ACK] always followed by [TCP DUP ACK] then [PSH, ACK] and [TCP Retransmission] before operation success. What could be these retransmission ?

Looks like your capture setup captured packets twice, so there are no real problems, just duplicates. See this blog post for details and solutions:
