That means, the server has maxed out the number of MySQL connections it allows.

mysql_connect(): Too many connections
The server has maxed out the number of MySQL connections it allows. You can try turning persistent connections off by adding this to your config.php:

$config['MasterServer']['usepconnect'] = 0;

But if you still have problems after that, you will need ask your host to raise the maximum number of connections they allow.

Here is more info on that error: MySQL :: MySQL 5.0 Reference Manual :: C.5.2.7 Too many connections

I would also research that ip address and maybe if needed block it if all the errors are from that same ip or ip range, here is the info on that ip in the error.
