udp will lose packege

[roninat]

If I create two tasks respectively at the same time, one using udp socket and the other using tcp socket, the priority of udp is high, and the sender sends for udp to receive approximately once every 10ms, but when I operate the netsocket_close of tcp to close the socket, It will lead to udp packet loss. How should I deal with it? And when sending data, it seems to also affect the reception of udp. can you help me ,thanks.
