Get errors trying to connet to localhost but localhost not defined in config

Hey

I just setup multi-db and moved the tables and made the config and mode the files as stated to wp-content.

There is no example on how to config if ONLY using remote mysql server, so i guessed.... i have added the databases using theese lines in db-config.php

add_db_server('global', 'dc1', 1, 1,'','192.168.0.198', 'wp_global', 'root', 'XXX');

add_db_server('00', 'dc1', 1, 1,'','192.168.0.198', 'bd_00', 'root', 'XXX');
add_db_server('01', 'dc1', 1, 1,'','192.168.0.198', 'bd_01', 'root', 'XXX');
add_db_server('02', 'dc1', 1, 1,'','192.168.0.198', 'bd_02', 'root', 'XXX');
add_db_server('03', 'dc1', 1, 1,'','192.168.0.198', 'bd_03', 'root', 'XXX');
add_db_server('04', 'dc1', 1, 1,'','192.168.0.198', 'bd_04', 'root', 'XXX');
add_db_server('05', 'dc1', 1, 1,'','192.168.0.198', 'bd_05', 'root', 'XXX');
add_db_server('06', 'dc1', 1, 1,'','192.168.0.198', 'bd_06', 'root', 'XXX');
add_db_server('07', 'dc1', 1, 1,'','192.168.0.198', 'bd_07', 'root', 'XXX');
add_db_server('08', 'dc1', 1, 1,'','192.168.0.198', 'bd_08', 'root', 'XXX');

in error log i get this error:

[Fri Apr 12 10:22:37 2013] [error] [client 127.0.0.1] FastCGI: server "/var/www/bloggersdelight.dk/web/php5.fcgi" stderr: PHP Warning: mysql_get_server_info(): Access denied for user 'www-data'@'localhost' (using password: NO) in /var/www/clients/client2/web1/bloggersdelight/wp-content/db.php on line 706

That line is

return preg_replace( '/[^0-9.].*/', '', mysql_get_server_info() );

Anyways, i have searched db.php and db-config.php for the string "localhost" and "127.0.0.1" with no matches... How come it tries to connect to localhost ?
