Search Filter process (Mssdmn.exe) maxes out CPU

  Asked By: Rocco    Date: Mar 04    Category: Sharepoint    Views: 4080

Has anyone seen this recent KB regarding SQL Full Text indexing
consuming the CPU capacity?

http://support.microsoft.com/kb/900390

I'm very interested if this could also be part of our problems with
Sharepoint indexing even though it is not listed as one of
the 'applies to' products.

We are experiencing the same issue on one of our indexing servers
and it creates a msssdmn.log file every 2 mins even though it is
empty. We cannot seem to complete an incremental crawl on a portal
index with only 2900 docs/6MG. The gather log is full of this error:

The address could not be found, (0x80040D7B - Document filtering
cannot be completed because the document server did not respond
within the specified timeout. Try crawling the server later, or
increase the timeout values.

Had a case opened with MS who said we had to have Win2003 SP1
installed. Changing the resource allocation to dedicated seem to
eliminate the problem for a while. But alas.....

yes i have sustained 20% cpu  usage divided between sqlsrvr.exe and mssearch.exe - and thats on a default portal build with NOTHING.

my variables (that i can see) are that we use MOM2005 and that sql  and sharepoint are running on the same box. this is our staging environment.

i have found nothing that has answered my question. im running SP4 on all my sql boxes.

SharePoint Portal server doesn’t use SQL Full Text indexing. Probably not the same issue.

The error you’ve indicated sort of looks like a backwards compatible document library issue… Do you have one setup?

Right, but does Portal Server indexing  use the same Office filters
referenced in the KB?

Yes, Full Text and SharePoint use the same IFilters. However, the package doesn’t appear to include the Office IFILTER. It looks like it’s only SQL components that were fixed … so I don’t believe it would have any impact.
