I'm using LWIP v2.1.3 with TI F28388D Controller. I'm using LWIP as TCP server only mostly in ping-pong mechanism like :
| Client | Server |
|---|---|
| PSH--> | |
| <-- ACK | |
| <-- PSH | |
| ACK--> |
A windows client(host PC typically) will be connected to multiple servers like this and will continuously have above transactions.
I'm able to connect and exchange data with multiple servers from single client but the problem here is If I run continuously for longer runs (>12HRs) I will see that any of the server will not respond for any of the commands from clients and there will not be response for PING aswell.
In wireshark capture I see that there will be TCP_retransmission packets when issue occurred like below: tcp retransmission
And I also see that there are tcp dup ack packets in regular intervals.
I can share the lwippopts.h file if required.
