What did you do?

I created two host inside mininet, one client and one server. The server is running caddy server with mp-quic options(-quic -mp) and the client is a dash client making https/2.0 request via mp-quic. every time i run the program this error happens.

The code I crated is base on mpquicScheduler(https://github.com/deradev/mpquicScheduler) adapted for 360 videos.

PS: sorry for the bad english i am not a native speaker.

What did you see happen?

What did you expect to see?

no error

[seankhliao]

sounds like it should be reported to github.com/lucas-clemente/quic-go

FYI I'm getting this same sporadic panic using github.com/imroc/req.
