Hi,

I'm trying to create an IP microphone server using sox-record and tcp-out node.

Everything works, i can connect from multiple computers using VLC. The tcp out node status shows "2 connections" for example.

But when i close one of the two VLC players, the status box drops to "0 connections" and the other VLC player stops receiving the stream. I can reconnect, but when i close a player, the other stops too.

Tested with 5 VLC instances too, tcp-out node shows 5 connections as expected and all of them are working. But:  
When I close one of them, sometimes an another VLC stops, the counter shows 3 connections after 5.

Is this a bug, or i miss something?
