High reject rate with 4.1.0-141-gc2c82 (ORIG: Rejected untracked stratum share from xxx) #136

Closed evolvia31 closed 10 years ago

Hi,

Since last month I use sgminer 4.1.0-73-g80e6 and all works fine.

This morning, i update my sgminer from master branch, compilation works with no error, the sgminer verison is: sgminer 4.1.0-141-gc2c82

But now, i have a lot's of this error: Rejected untracked stratum share from xxxxx On the pool side, this reject aren't detect but on sgminer side the general reject count increase to obtain 25% of rejects.

I try to switch with my old sgminer (sgminer 4.1.0-73-g80e6) and I don't have this reject.

So what's the problem ?

Why one sgminer detect untracked stratum share and not the other ? Why the last version detect untracked stratum share as Reject and not the pool ?

My OS is: Ubuntu 13.10 (GNU/Linux 3.11.0-15-generic x86_64)

Thank you to your help :)

TBH, I have no idea. Is this still present with latest git master?

4.1.153 also suffers from this issue (or a similar one). The number of rejects is many times higher than with cgminer 3.7.2. When you subtract the rejects from totals cgminer is substantially faster than sgminer, even though sgminer yields a faster hash rate on ATI cards.

Cannot reproduce. Could this be specific to some OS / driver / hardware / configuration, or a combination of them?

Hi, I just download and compile the last release and my problem is finished. i can't reproduce this bug with the new release of sgminer. For me bug is over :)

I will re-test with the latest git version tonight.

I can confirm that the latest git master sgminer (4.1.242+) now produces approximately the same degree of rejects (~1%) and same performance as cgminer 3.7.2 with same parameters.
