Charlie,
Yes, I do. First of all, what is the exact version of SQL Server (7.0 or
2000) and on what OS platform is it deployed? Could you post the full output
of -- SELECT @@version -- as this is VERY helpful information in
troubleshooting such SQL FTS performance issues!

Secondly, and depending upon what your is your SQL Server version and SP
level as well as the exact query that your are getting these errors, you may
want to checkout KB article 818883 "PRB: You may receive error 7619 when you
run a full-text query that contains many OR operators in the search string"
at http://support.microsoft.com/default.aspx?scid=kb;en-us;818883 as one of
the symptoms is error: "Not enough storage is available to complete this
operation" as this occurs on SQL Server 2000 SP3 and when your CONTAINS
query contains many logical OR operators.

However, because of the larger number of rows (30 million), in your
FT-enable table, you may have encountered additional problems related to the
Master Merge. Specifically, you should review your server's Application
Event log for "Microsoft Search" or MssCi source events - errors, warnings
AND informational for any related Master Merge paused conditions.
Furthermore, you should review the Performance Monitor (Perfmon) counters
for Microsoft Gatherer: Reason to back off, Microsoft Gatherer Projects:
Gatherer Paused Flag, and Microsoft Search Indexer Catalogs: Merge Progress
to determine if there is an existing issue with the Master Merge process.

Depending upon your reply, I can provide you with more specific
recommendations.
Thanks,
John
