mysql_pconnect give always trouble because of using persistant connection and what usually happen is error and it is better to disable it:
Code:
Warning: Too many connections in /usr/www/users/xxxxx/includes/phpconfig.php on line 4
Warning: MySQL Connection Failed: Too many connections in /usr/www/users/xxxxx/includes/phpconfig.php on line 4
It is because of max_user_connection variable int MySql that is always limited to save resource of server.
