When a failure occurs in a file object, that will be marked as a fail record and will be moved to location (configured by the user) where move error file objects are kept. The failed record will be maintained inside a text file (file name is configurable) and the location of that file will be provided by the user. When the next polling iteration is going on, it will check the file against the failed record and if the file is a failed record, it will skip processing and schedule a move task to move that file (the retry duration of the file move task can be configured). It's handled this way because it is a random failure in the move operation.
