Database error (need help)
 

I get email from database :

75 inbox all the messages is same error.

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: http://dev.mysql.com/doc/refman/5.0/...nnections.html

i see in my config.php
$config['MasterServer']['usepconnect'] = 0;
so i must change the number or what?
i take dedicated server for this.

That means it is off, and as Marco has mentioned, you will need to ask your host to raise the maximum number of connections they allow.

Its because my visit connection / inactive user reminder emails or what?
i have 15k members.

It means there are too many people accessing the database, ie. many visitors.

so the visitor visit my site was limited if i change the settingS?

I do not understand your English. The error says that too many people are accessing the database at the same time.
