I think it's an issue with the pool rather than with your miner.  I was mining here without a problem until there was a sudden "bug" that jumped my rejects from <5% to >60%.  Our op said that this was an unintentional bug that would be fixed within a couple of hours.  I tried for a bit for a couple days afterward and the rejects continued.  I switched my miners over to a different pool and all settings worked normally with minimal rejects.

I keep checking back here to see if the reject complaints die down because I really like this site and pool.  But I think it's going to take an "aha" moment from the hosts before I can jump back in.

I tried again this morning and I'm hitting about 70% rejects.

Ok.  Thanks for the quick response.  Bugs happen.

I've noticed a huge increase in duplicate/rejected shares over the last couple of hours.  I was mining happily before that so I don't think it's a miner setup issue.  Anybody else seeing high rejects?  I'm getting 60+%
