Landing in any one of the above scenarios without knowing when the DBCC CHECKDB process might complete will land any DBA into a miserable state. DBCC CHECKDB was causing several resource crunches on the server, and you prefer to stop it, impacting the server's performance.DBCC CHECKDB execution waiting on some other process or long-running queries to complete for a long time to start crash recovery.
Ad hoc execution of DBCC CHECKDB on a Production database running for a longer time and DBCC CHECKDB was never executed on the database before.Scheduled DBCC CHECKDB execution running for longer than the average execution time.Let’s say a DBCC CHECKDB was executing on a database for a long time, and it meets any of the below scenarios: How DBCC CHECKDB ends up in a Killed/Rollback state? Once the tests are completed, Internal Database Snapshots will be dropped out. Performing Logical and Physical Integrity Checks on Internal Database Snapshots helps avoid the Blocking and Concurrency issues on the database. (SQL Server 2000 and earlier use a different logic to perform DBCC CHECKDB) For crash recovery, uncommitted transactions in the target database are rolled back in the internal database snapshot to give a transactionally consistent database view. Starting from SQL Server 2005 onwards, executing DBCC CHECKDB on a database uses an Internal Database Snapshot to run a crash recovery of the database. The DBCC CHECKDB is a Database Console Command (DBCC) to verify the Logical and Physical Integrity of all objects inside the specified database.

In this article, we dive into detail on how the DBCC CHECKDB command works and how to resolve the DBCC CHECKDB process stuck in Killed/Rollback. However, if the DBCC CHECKDB executes for a long time, many DBA's get panicked, and you have decided to cancel the DBCC CHECKDB execution, then you can end up with a DBCC CHECKDB command stuck in a Killed/Rollback state. Every DBA would have scheduled a DBCC CHECKDB in their Production environments at some time and would have executed DBCC CHECKDB commands on Production databases whenever there is any suspicion of corruption. One of the primary responsibilities of a DBA is to ensure Database integrity.
