sa_diagnostic_blocking table

The sa_diagnostic_blocking table is owned by the dbo user, and records blocking events. If logging of blocking events is enabled, a row is inserted in this table each time a connection is blocked while trying to access a resource. Typically, this is caused by either a table or a row lock. A large number of blocks may indicate that you should examine the concurrency in your application to reduce contention for tables and rows.

There are two versions of this table: sa_diagnostic_blocking, and sa_tmp_diagnostic_blocking.
