Problema conection

No meu site quando clico rápido em vários links aparecem esses erros

Warning: mysql_pconnect(): Link to server lost, unable to reconnect in /home/u685780688/public_html/Connections/conection1.php on line 9 Fatal error: in /home/u685780688/public_html/Connections/conection1.php on line 9

e esse

Warning: mysql_pconnect(): User u685780688_root already has more than 'max_user_connections' active connections in /home/u685780688/public_html/Connections/conection1.php on line 9 Fatal error: User u685780688_root already has more than 'max_user_connections' active connections in /home/u685780688/public_html/Connections/conection1.php on line 9

Eu não sei oque pode estar causando isso e muito menos como arrumar alguem já teve esse problema ?
