Just a small question: I started mining on this pool over 12 hours ago and there were no stale shares (my config files includes the parameter "--no-submit-stale") but suddenly a few hours back my stats started giving stale percentage varying from 3-6%. How come all of a sudden such stale rate popped in, and when I've the correct parameter in place to avoid such thing?? I'm a bit newbie to this, so sorry for asking this noob question.
Thank you
Get rid of --no-submit-stale.
Mining software (CGMiner, SGMiner, etc) expect a single Blockchain not multiple changing ones on coin switching pools. They'll think shares are stale when they are perfectly valid. So you should always submit everything on multi-coin pools or you'll be throwing perfectly good work away.
That also goes for p2pool nodes as well.
