I send raw PCM samples through a websocket (on a local machine via loopback or between two machines) where those are analysed in realtime by a receiving process. And my transmission consistently keeps breaking with the “broken pipe” message and both ends report that the failure was unexpected. When analysing the packet data using Wireshark I see many “TCP window set by the receiver is now completely full” messages. Wondering if these two phenomena are related to each other (I suspect they are) and how I can fix the problem.
