SYMPTOMS

Consider the following scenario:
  • You enable the Change Tracking and Auto Cleanup properties for a database in Microsoft SQL Server 2008.

    Note The Auto Cleanup property automatically cleans up the data for change tracking.
  • You set the Retention Period and Retention Period Units properties.
In this scenario, the sys.syscommittab system table for change tracking is not cleaned up after the specified retention period.

Notes
  • To list the latest committed transactions from change tracking, run the following query. If a transaction is older than the retention period, this issue has occurred.
    Use <Database Name>
    select top 10 * from sys.dm_tran_commit_table order by commit_time
  • To return the disk space that is used for the sys.syscommittab system table, connect to the server by using the dedicated administrator connection (DAC), and then run the following query:
    sp_spaceused 'sys.syscommittab'
