In vCenter Chargeback 1.5, there are reports that are queued and unprocessed. After upgrading to vCenter Chargeback Manager 2.5, these unprocessed reports are listed on the Running Reports page of the Reports tab.
These reports are stale and inactive.
Additionally, newly generated reports are not listed on the Running Reports page.

In reports tab it lists stale and inactive reports but does not include new reports

1. Stop the vCenter Chargeback Manager service and the corresponding data collector services.
2. In the vCenter Chargeback Manager database, run the following SQL query:
UPDATE CB_TASK_QUEUE SET TASK_STATUS = 'ERROR' WHERE TASK_STATUS = 'IN_PROGRESS' AND MODIFIED_ON IS NULL
