  Hi team,
            we are encountering in our project, which involves data
transmission using the LWIP stack with the UDP protocol.
1)Source IP Address (Board): 192.168.1.1
2)Destination IP Address (Board): 192.168.1.255 (Broadcast)
3)Monitoring Laptop or pc IP Address: 192.168.1.50

We have configured our system to continuously transmit data from the board to
the monitoring laptop or pc. The data transmission works correctly some time;
however, we face intermittent issues when the laptop or pc provides mDNS
(Multicast DNS) services to the board. During these instances, data
transmission errors occur, causing interruptions.

This problem is not consistent across all systems. While some systems continue
to transmit data 

 Below attached screenshot from Wireshark that captures the error occurring
during data transmission.


Thanks & Regards,
Aravind
