client can not recreate connection with coap server

[ls327782081]

i can not find how to release ClientConn in server's conns.when client down, the server can not write response to client than it use cancle function but the ClientConn still in server's conns. The next time, client recreate connection with the server, the server do not create ClientConn but get it from server's conns,it cause ClientConn's context is cancle

Hi.

• How did you initialize server - which paramters -> Is it keepalive enabled ?
• Could you create a test for reproduce the issue / a sample code ?

Thx

i set keepalive nil
s := udp.NewServer(udp.WithMux(mux), udp.WithTransmission(time.Duration(transmissionTimeout)time.Second, 2time.Duration(transmissionTimeout)*time.Second, transmissionMaxRetrans), udp.WithBlockwise(true, blockwise.SZX1024, time.Duration(transmissionTimeout)*time.Second), udp.WithContext(ctx))

s := udp.NewServer(udp.WithMux(mux), udp.WithTransmission(time.Duration(transmissionTimeout)*time.Second, 2*time.Duration(transmissionTimeout)*time.Second, transmissionMaxRetrans), udp.WithBlockwise(true, blockwise.SZX1024, time.Duration(transmissionTimeout)*time.Second), udp.WithContext(ctx), udp.WithKeepAlive(nil))
