We are running mediasoup 3.8.4
Any direction on this would be much appreciated
I’d check your code first and foremost, soup isn’t likely to fail all at once like that and it’d suggest runtime errors or other issues not necessarily logged because it may be your code somewhere doing it!
Were you able to get it sorted? If so what was your issue? 
yes I was it was a socket.4.2 issue. basically the socket was closing. Looks like there is a change is socket 4.20 vs socket 2.3 which we were using , in 4.20 the server sends the ping messages and they were timming out therefore dropping the connection and restarting ICE.
Thank you for you help
