I was previously running 0.9.7 and getting rejected shares in the 3%-4% range which is not out of line. However, now running both 0.9.7 and 0.9.14 the rejected shares have sky rocketed to the 10% to 10.5% range. Just wondering what has recently happened? Occurs now on both my AMD 560/580 rigs.
Man, this is too high values. Even 3%-4% not good. Can you update to newer version? 0.9.16 should reduce a bit. Also, what intensity do you use?
Okay, I recheck and on my 3-560/1-580 rig it was 11.5% rejected shares running 0.9.7 and on the 1-560/5-580 rig it was 1.3% rejection running 0.9.14.
I just load and running 0.9.16 and so far after submitting 500 shares the 3-560/1-580 rig now has 1% rejected shares and the other rig down to just 0.5% rejected shares. So looking good.
I run the 560s at 256 and 580s at 512 intensity respectively.
The other odd quirk is I tested port 7777 on the slower 5 Mh/s rig (3-560/1-580) and it cannot hash at all with 0.9.16 ... only works on port 5555 on Purk pool.
Okay, after some further testing some weird stuff occurs.
One rig (3-560/1-580) hashes away just fine for nearly 1,000 submitted shares after 3.5 hours at just 1% rejection rate and around that time suddenly the rejection rate sky rockets with lots of "low difficulty shares" rejected and also "stale shares ... ignore it" that take the rejection rate above 10%. I basically just close and restart the miner and it likely will be fine again for the initial few hours.
On my other rig (1-560/5-580) it is working a bit better at also roughly 1% rejection rate, but then encountered inability to find mining pools and some disconnects/reconnects including a 3 minute span that resulted in over 30 rejected shares consecutively that caused the miner to restart.
Cannot figure out how to paste a picture so here is some text on the errors:
