The last few days I've setup some graphs of Wowza connection info.
It seems that the active connections to our VOD content are a lot higher than might be expected. After some investigation I found the serverinfo HTTPProvider, which reveals that there are clients which have been connected for weeks.
Are there any mechanisms for timing out or disconnecting clients which have been connected for more than, say, a few hours?
Which Wowza version are you using? There was a similar issue that was fixed in the Wowza later releases. Can you upgrade your Wowza Streaming Engine version to the latest release and check if you have the same problem?
In the "
Latest Production Build" forum article you can find instructions on how to downlaod and upgrade your server to the latest version.
