Carbon Black App Control (formerly Cb Protection)


  • Events are seen in the Console with an error similar to:
  • "Database data file size limit reached. Total data file size is 3077 MB."


  • App Control Server: All Supported Versions
  • SQL Server Express Edition: All Supported Versions


SQL Server Express Edition has a maximum database file size of 10GB. App Control will default to a cutoff size of 3.7GB (3700MB) when SQL Server Express Edition is used.


To increase the allowed database size:
  1. Login to the Console and navigate to: https://ServerAddress/shepherd_config.php
  2. Locate the Defined Property: MaxDatabaseSizeMB and change the Value to: 8192
  3. Click Change to save the new setting.

Additional Information

  • If it is expected that the database size will continue to grow beyond 10GB, an upgrade to SQL Server Standard Edition will be required.
  • The Alert is configured to warn when the database is approaching the limit.
  • The Shepherd Config Property, DisableTrackingCutoffDatabaseSizeMB may need to be adjusted as well.
