Looks like a bunch of bitfinex customers are stuck with a 0-confirmation withdrawal for the last 10(?) hours or so:
https://www.blocktrail.com/BTC/tx/2e9ceda8a520f4d0deca82158cfb389848575f505e6f5e9b2011c152918de146~1736 BTC in this transaction and others hanging from it. Looks like it currently has 2 unconfirmed inputs, so the delay is likely further back the line.
Anyone know enough blockchain-fu to understand what's going on here?
(I'm one of the people affected by this - my wallet is showing this tx as 'conflicted')
Yes, another annoying stresstest done to proof that we need bigger blocks to protect against blockchain spam. They do this since yesterday.
