Symptoms
In the event log/critical/minor failures there are old failed tasks, that are related to already processed documents, e.g.
Event type CC processing request, Task ETransactionCapture fails with
Execution Failed: Payment #ID is already processed.
Cause
Events/tasks relate to already completed document, no further changes are required to the document.
Resolution
If there are logs available for a period when the payment was made and processed, try to identify the cause of the failed task.
- Make sure that the payment with ID mention is successfully processed and no further actions are required.
- Delete the failed task, an event will change its status to 'canceled'.
