Here is an interesting support call where Change Data Capture (CDC) log scan job was failing with error below.


Executed as user: domain\svc_account. Log Scan process failed in processing log records. Refer to previous errors in the current session to identify the cause and correct any associated problems. [SQLSTATE 42000] (Error 22859)  The statement has been terminated. [SQLSTATE 42000] (Error 3621)  Could not open File Control Block (FCB) for invalid file ID 0 in database ‘TEST_DB‘. Verify the file location. Execute DBCC CHECKDB. [SQLSTATE HY000] (Error 5180)  The call to sp_MScdc_capture_job by the Capture Job for database ‘TEST_DB’ failed. Look at previous errors for the cause of the failure. [SQLSTATE 42000] (Error 22864).  NOTE: The step was retried the requested number of times (10) without succeeding.  The step failed.

Enabled CDC on a Test database on the same instance of SQL Server. This creates several CDC related tables including cdc.index_columns in the Test database. Scripted out the definition of the index using SSMS and added the index back:
