No issues here... Do you by any chance have also LTC config and you have just switch back to BTC? I know that someone did scrypt mining on this pool some time back...
No, nothing like that. I configure everything from a batch file. I am seeing a lot of "Stratum connection to pool 0 interrupted" errors, and then all shares are rejected after that until the pool connects again. The other thing I don't do is manually set my difficulty. I noticed others here are doing that, but is it necessary? My rigs range from about 800 MH/s to 1.8 GH/s.
