Do you have a maintenanceplan that rebuilds the indexes during the weekend, but monday morning all clients complaints that the system is saying “Not responding”. When you look at the database you can see that the Rebuild indexes hasn’t finished because some process was blocking.
If you are using the “Execute T-SQL Statement Task” then you can setup the plan to send you an email if the job isn’t finished after x seconds.
The script below rebuild all indexes in all userdatabases and update statistics.
