When this situation exists, one task is queued to immediately follow the other task.
You can select to enable Damage Cleanup Services for tasks that perform the following actions:
Assessment only: the shared task performs both a Vulnerability Assessment and a Damage Cleanup Services assessment. It does not perform any cleanup functions.
Cleanup: the shared task performs a Vulnerability Assessment and a Damage Cleanup Services assessment. It also performs cleanup services on any damage it finds on the machines.
Refer to Using Damage Cleanup Services for more information about the Damage Cleanup Services assessment and cleanup functions.
