I am consistently getting "more than 'max_user_connections' active connections in" .. errors from the ProPlayer playlist-controller.php file.
It seems to use mysql_pconnect() to find a persistent sql connection.
However, there is no cleanup anywhere in the plugin and the database connection is never closed.
I've hacked the code and changed the mysql_pconnect() to mysql_connect() for the time being. At least that will close down some connections after a perdiod of inactivity on the server.
Can the author please update the plugin with an appropriate desconstructor class that closes the mysql connection.
