Spidering returns no results

[toddvirgil]

When I try to spider my site on our Rackspace dedicated host (dedicated but there are multiple sites on the same machine) it will not index. When I spider any of the sites on the same server, they will not index. However, when I spider sites on other servers, it works well.

It returns the following message:
Optimizing tables...
Indexing complete !

But does not index any files or keywords.

My open_basedir is set to:
/home/httpd/vhosts/neurologicalresource.org/httpdocs:/tmp

Any Ideas?

Thanks!

By the way, the server is not load-balanced. It does however have a firewall box attached.

The following settings have been made:

define('LIMIT_TO_DIRECTORY',false);
define('PHPDIG_IN_DOMAIN',true);
