11/18/2022, 7:40 PMthat’s a bit out of my expertise, but I’m not seeing that error in our codebase

11/18/2022, 7:44 PMhere we go, I think its coming from pion/TURN: https://github.com/pion/turn/blob/40ee5ed2f3ebf77582e41336b90be73cb90ee283/internal/server/server.go#L74

11/20/2022, 6:25 PMHi, multiple participants have different names in our app. I reproduced the issue load testing with 500x livekit-cli instances tasks: total=500x rooms and 5/5 pubs/subs per room with ~10m ramp up. It seems there's some overlaping in dynamic port allocation, Does this makes sense?

11/21/2022, 4:38 PMInteresting… I’ve never seen this issue before. But its possible we just haven’t tested the TURN component as thoroughly. We’ll have to look into this some more. (cc @dry-elephant-14928 in case you have a better sense for why this is happening)

11/22/2022, 8:32 AM@polite-printer-17791 Is this actually causing any client failures for you? It's possible this is happening only due to the frequent connection/disconnections between load tester clients

11/22/2022, 4:57 PMHi, currently no customer impact. We are preparing for football matches that induce high demand in short time. The issue is hapening in peak load testing. I see new rooms beeing allocated to already congested nodes and that is something we seak to avoid. That may be a reason to see this error.
