Almost done installing. Need help!

I have installed WP MU with MultiDB on a dedicated server. I am having som issues.

When creating a new blog and click view / edit that blog, I get the following error:

Warning: Invalid argument supplied for foreach() in /mnt/webstorage/I/ipublish/www/wp-admin/wpmu-blogs.php on line 147

I suspect this has to do with the "global" settings.

define ('DB_SCALING', '256');
add_dc_ip('', 'dc1');

add_db_server('global', 'dc1', 1, 1,'localhost','localhost', 'ipublish_MU', 'ipub2', 'xxxxxxxxxxx');

add_db_server('00', 'dc1', 1, 1,'localhost','localhost', 'wpmu_00', 'ipub2', 'xxxxxxxxxxx');
add_db_server('01', 'dc1', 1, 1,'localhost','localhost', 'wpmu_01', 'ipub2', 'xxxxxxxxxxx');
add_db_server('ipub3', 'dc1', 1, 1,'localhost','localhost', 'ipub3', 'ipub2', 'xxxxxxxxxxx');

add_vip_blog(1, 'ipub3');

All the databases has been created. The global database name is: global_wpmu

When make changes to this:
add_db_server('global', 'dc1', 1, 1,'localhost','localhost', 'ipublish_MU', 'ipub2', 'xxxxxxxxxxx');

The entire site goes down, showing error message of enless loop.

Any help and suggestions will be greatly appreciated.

Thanks in advance.
