[lwip-users] Retransmission of a already acknowlegded package.

[Christian]

Hi,

I'm using lwip141 in NO_SYS mode.
In random intervals a retransmission happens for a already acknowlegded
package. After that a dupack package gets send.
I've attached a Wireshark capture where you can see this at package 1516.

What can be the reason for this behaviour?
Thank you
BR
