Full Text Max Size?

Hi,

Does anyone have experience with Full Text catalogs on large tables? We have a full text catalog on a table with about 30 million rows. Acording to BOL, once you get over 1 million you'll need to make some adjustements. Our system works, but we randomly get the following errors with ad hoc queries. The server has 8GB of RAM and 4 3GHz processors. Does anyone have experience working with a table this big? Any suggetions as to what could cause these errors? The only thing I could find was BUG#: 469483 on MS's site, but we're not using any OR clauses

Thanks

Here's the errors....

SELECT * FROM acc_results ar
WHERE CONTAINS(finding_text, 'cell')
