Mssearch.exe consuming High CPU over extended time period

Hello,
We are running SQL 2000 sp4 with full text search, recently we are
getting 100% CPU over extended period of time and the only way to
resolve this is by killing the Mssearch.exe process. (we tried to
restart the service but it hang) the Microsoft search service is
running under local system account.
our system topology is active/passive cluster with NAS disks, 4GB RAM
and 4 CPU for each server.
May be some one can help me?
The issue happen randomly with no specific job running at that time or
any thing, and when it happen the SQL queries are running very very
slow.
Thank you

No solution to your particular problem, except looking at a prioir post:

In your particular case, when did the problem start? After upgrade, some configuration change, resource change, database size change?

This may help understand the problem.

Thanks,

We appear to be experiencing the same thing. There is no disk activity - just mssearch running at 100% utilization.
Have you found an answer yet?
|||We used Microsoft support and nothing found we tried rebuild all catalogs , Fix some snapshot problem on the NAS and still we got the same problem finally we changed the affinity mask of the Mssearch and the SQL (SQL use CPU 1 and 2 and Mssearch the rest) we are still waiting to see if it help to solve the problem for now (4 days) it look fine even though the Mssearch took 100% the SQL continue to give services and the CPU drop back to normal with out human interference. So I will have more clear answer with in a week.
