Why have an issue? It's P2pool.

Also this hashrate is very interesting. I think someone testing their whole datacenter on the pool.

Because 2 XEON Servers can only give around 10KH in this algo.
OMG!
Local rate: 413.79 KH/s (DOA 173.44 KH/s / 41.91%)
Global pool rate: 412.20 KH/s (DOA 151.18 KH/s / 36.68%)
Now our pool holds the entire p2pool network.

Will the address with the huge hash have an issue getting paid?
