Renter UNOE111I've tried IRC to see if you were on there, but no luck, so I hope that you see this here.
Currently you are renting HashMaster9 and it's mining a difficulty 9 coin. I don't know which pool you're using, but the pool's Vardiff implementation is setting insane work difficulty requirements for a coin with such low difficulty and fast block times:
[15:12:19] Pool 0 difficulty changed to 4019.481559
[15:12:22] Pool 0 difficulty changed to 7189.504934
[15:12:24] Pool 0 difficulty changed to 10296.367546
[15:12:31] Pool 0 difficulty changed to 2549.084913
[15:12:36] Pool 0 difficulty changed to 5240.731769
There's just no way without incredible luck that such high work difficulty levels can be met when blocks are taking 5-7 seconds to solve. This is leading to very high reject levels and a low work utility vs hash rate. Please either contact the pool's operators and ask them to fix their Vardiff, or look for a better pool to mine the coin. I hate to see the rental time being wasted like this

same here... causes 1.6-2.7% rejects....
not much I can do about that. choose better coins, or live with it ;-)
