You have to localize the scope of the new hash that you are creating 
using 'my'. If you don't then a new hash isn't created for each iteration.

while (@ary = $sth->fetchrow_array ())
{
     my %hash = (
         base_url    =>  $ary[1],
	max_depth => $ary[2],
     );
     push @servers, \%hash;
}
