Hi I'm using STM32F439 Dev Board and LWIP as TCP/IP stack; I'm using TCP echo server example. the board is connected to PC. when I send a message from PC to the board, it echoes back the message. But there is a problem. after sending exactly 1000 messages I don't receive the message from the board anymore. I used RAW and NETCONN API and both of them had the same problem. The problem For UDP echo server/client there isn't. Please help me to resolve this issue
