FT Locks the table!



FT Locks the table! Mike Kansky

sql server full text search: I have a table with Full Text index on it, the table has at the most 300
records.
The database is on the live server and gets hit a lot.

Every morning when i come to work the table is inaccessible, meaning any
query that i issue to this table runs indefinitely, Select, update, Insert
all just hang.

The only way for me to fix this is manually End The Full Text Sql Windows
Task, in task manager. As soon as i end the task it restarts immediately and
everything is working fine after.

Is there a patch for Sql 2005 to fix this, did anyone experience something
like that?

Thank you Hilary.
I checked and i have the change tracking set to Auto.
I cannot find where i can change the resource usage for FT.
Can you help please?

It is Sql 2005.

Full-text indexing will cause some locking as it needs to create some level
of consistency with what is in the catalogs and what is in the database. Are
you using change tracking? If not you really should. You also might want to
set your resource usage to something smaller.

One more point, it is possible that other non-optimal procs or ad hoq sql
statements are themselves not tuned and are causing overall performance
problems manifesting itself in FTI locking.
