The processor 'paymentStatusCheckProcessor' runs 4 times a day to check the status of payment txns.
When a payment txn was updated with a wrong status due to a server/connection issue from salesforce or payment gateway, this is then checked from the payment gateway and corrected.
In normal circumstances, this is as rare as 1 in a million.
This is an added check for payment txns, so it is not something to worry about. This is not recharging the payment txn or recurring payment (incase the payment txn was made from a recurring payment). This processor is just correcting the status.
