I have an issue where the Helix server dies and restarts. I noticed that although the principle way that the user workstation receives the streaming video is via TCP->HTTP->RTSP netstat reports the UDP has no ports and it increases on average of 4 "No Ports" messages a second. The server pauses communications to workstation and reports network issues in the log. Does anyone know whether the RealNetwork's Helix Server uses UDP sockets...
