The transaction was sent to me by a third party. I had ZERO to do with it. I'm just sitting here waiting for it to be confirmed in my wallet. There is nothing more complicated than that. I appreciate all your input but I'm not sure if you are chasing a red herring here or what. All I know is that this sort of thing as NEVER happened before.
Sorry, there's been a lot of shit to read though in this thread, so I missed the part where this was a transaction you are receiving and not one you are sending.
The person that sent the transaction to you either screwed up, or is intentionally attempting to send you a transaction that will never confirm. It isn't possible to tell which it is from the information you've provided so far.
Specifically:
They spent unconfirmed funds in the transaction that they sent you.
This could happen accidentally if they are using a poorly written wallet.
It can also happen intentionally if they were hoping that you'd send them something of value before the transaction confirms. They would then have an opportunity to try to re-use the same inputs in a different transaction so that the transaction that they sent to you vanishes and ceases to exist if their competing transaction gets confirmed.
Contact whomever sent you the transaction. Let them know that the 2.142 BTC that they received at address 1KfncRtWe8ycboDe1BAw4UyFBrgpZRHwpN were unconfirmed when they used those bitcoins in the transaction to you. They should contact whomever sent them those 2.142 BTC and complain that the transaction didn't include a transaction fee and hasn't confirmed.
Let them know that their transaction to you WILL NOT confirm until AFTER the transaction where they received 2.142 BTC confirms.
