Could it be that Antpool is simply not listing their orphans? The issue appears to be spreading accross more pools: https://github.com/dashpay/p2pool-dash/issues/43

You will get your payout but there's no need to attack me. I've worked on the issue until 5 in the morning when I collapsed into my bed. It's hard to solve a problem which you have no reasonable explanation for.

They have like 50x our hashrate.

I doubt that. Both the daemon and the pool are running on a dedicated 8 core server having a 1 GBit connection each. Latency from pool to daemon is less than 1ms.

What do you mean?

Got a link to ZPool's statement?

Tried that almost a day ago.

Looks like we are not alone: https://github.com/dashpay/dash/issues/1822
