Grid task fails to complete and moves to Historical table

In some cases, you might observe that a grid task moves to the Historical table without completing successfully.

If a grid task fails to finish successfully, it moves to the Historical table with one of the following statuses:

Aborted: The grid task did not complete normally and had to be aborted.
Rollback Failed: The grid task did not complete normally and failed to be aborted.
Cancelled: The grid task was cancelled before being started.
Expired: The grid task expired before completing.
Invalid: The grid task was not valid.
Unauthorized: The grid task failed authorization.
Duplicate: The grid task was a duplicate.

Grid task expiration is most common reason for a grid task to fail. If a grid task expires, it can never be run. A new grid task must be created and run.

Note that a grid task failure is not the same as a grid task error. If a grid task encounters an error, it remains in the Active table. Its status changes to Error and then to Retrying as it attempts to finish. A grid task that has an error does not move to the Historical table unless it is aborted.
