hi we’re using a single instance of wowza, rtsp broadcasters (50 to 100 simultaneous), player clients using rtsp and coupertino streams, multiple times a day wowza needs restart, because ports reaches 65k+.

In Server.xml what do you have RTP/DatagramStartingPort. The default settings is 6970. This instructs Wowza to use the UDP port range: 6970 to 65535. Each stream should use 4 ports. We recycle ports after they are used. There is a timeout period of 10 minutes before a port is recycled. If you are only stream to a few hundred concurrents it should take a long time to run out of ports. You can certainly shorten the timeout period to say 1 minute to see if that helps: ```auto UDPPortManager udpPortManager = Server.getInstance().getUDPPortManager(); udpPortManager.setPortRecycleTime(1*60*1000); // one minute in milliseconds ``` Charlie Charlie ---

default configuration: 6970 false streams came from outdoor cameras, sometimes very bugous, and in this case, our converter may restarts the broadcast sessions up to 4-5times in a minute. i will try decrease the port recycle time, thanks Charlie.
