Increase or disable blocked process threshold

  • Makale

Applies to: SQL Server

This rules checks that the blocked process threshold option is set to 0 (disabled) or set to a value higher than or equal to 5 (seconds). Setting the blocked process threshold option to a value from 1 to 4 can cause the deadlock monitor to run constantly. Values 1 to 4 should only be used for troubleshooting, and never long term or in a production environment without the assistance of Microsoft Customer Service and Support.

Best practices recommendations

To resolve this problem, set the blocked process threshold option to a value of 5 (seconds) or higher, or disable blocked process threshold by setting the value to 0. To set the blocked process threshold to a value of 5 seconds, execute the following statement:

sp_configure 'show advanced options', 1 ;
GO
RECONFIGURE ;
GO
sp_configure 'blocked process threshold', 5 ;
GO
RECONFIGURE ;
GO
