Just going to re-confirm that my divs haven't been received on my address. I wonder if its because I only have a single share--is the div big enough to be accepted by the network?
Yes, this has been stated before. Divs on one single share are less than tx fee. Earlier someone said you can plug your receiving address into block chain io and see that you are accounted for. Did you try that?
Double checked on blockchain.info, triple checked the confirmation email that transferred my havelock share to direct share. The address checks out--but there's no unconfirmed/confirmed dividends received. I only have one transaction on the address (cold storage transfer in), so I'm sure I didn't miss it. Spooky!
Short explanation: ASICminer tried to send the minimum amount, as it was only for administrative purposes. The minimum amount per output accepted by the network is regulated by the "dust threshold": any output smaller than this threshold, and the transaction will not be accepted (it's considered to be spam).
Unfortunately, there's a very common misconception that this threshold is 5430 satoshis, while in reality it's 5460 satoshis. So ASICminer used the wrong value as dividend in their attempt to send the minimal amount. Doesn't affect you if you have more than one share, obviously.
No idea why they didn't notice their mistake though, as submitting the transaction with a wrong output would fail.
