# It seems that there is a race condition on SQL Server startup that does not allow CDC to be enabled immediately. The following error is returned instead:
# > 'Could not update the metadata that indicates database test is enabled for Change Data Capture.
# > The failure occurred when executing the command 'sp_addrolemember 'db_owner', 'cdc''.
# > The error returned was 1205: 'Transaction (Process ID 52) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.
# > Rerun the transaction.'. Use the action and error to determine the cause of the failure and resubmit the request.'
