Hi terk

since 14h30 GMT +1 i have enormous fail on the pool

Is it normal, cgminer lost connection to stratum server every 10mins

Please read the thread before post! There's an issue on the server, Terk is working hard to set another one!

[igroock]

I'm setting up more powerful server as I write this. Should be able to switch to it within 1-2 hours. Hostname and IP won't change so you can continue mining, you will just get disconnected and then connect immediately again to the new server.

Is this the server in CA you were planning to move to?

I am currently on Waffle but want to give your pool another try. I got passed the rejection rates, the biggest issue my Hash rate constantly drops. Will the new server fix this? I woke up today to find 2 of my rigs sitting at 40kh per card, when it should be at 700+.

Thanks for the updates.

500KH/s were my hashrate normally lies around 1500KH/s, getting lots of disconnects and rejected percentage is shifting between 2-40% I'm stationed in Europe.

Hope stuff gets fixed soon, was a very good pool. Until then I'll be on another pool.

Same here, this is definitely going to be my primary pool once these issues are sorted out. For the time being I'm going to mine some DOGE coins as they seem to be quite profitable for the time being. Will check back every so often. Good luck Terk with the new server etc.

1. My rejection Rate is very High bRejected: 83.9 kH/s (13.8%)

2. I am running Sapphire R9 280X. The cgminer show avg 728 KH/s where as on the website 631.7 kH/s 24-hour Average.

3. As per the website  the  BTC per day is 0.01218 BTC/day per MH/s.Based on this calculation the BTC/day for 700 KH/s must be .008526. However i have only 0.00565835 BTC. i e 34% less than pool profitability.

Please advise

Raw hashrate is 728 kh/s. Rejects are 13.8%. 728 kh/s * (1 - 0.138) = 628 kh/s effective. Pretty much exactly what you're seeing.
And I got the same BTC/MH yesterday. Seemed to be a lower-than-average profitability day.

To everyone struggling with very high rejects: You can tweak cgminer to use a lower intensity while still maintaining a high hashrate via the -g 2 parameter. But that will only help if your rejects are actually higher than the pool average. If it's already equal or lower than average, then you don't really need to worry about it because the reject rate is already factored in the profitability calculation, according to Terk.

Forgive me but where is the pool average for rejects? I am at 24% rejects which can't be right! When you use the g2 parameter are there any general rules of thumb? For instance do you usually start with half the -I and -g2?
Thanks in advance.

Average rejects are displayed alongside your own rejects in the graph on your user stats page. Right now it's about 25%, so yours isn't even particularly bad.

Yeah It will be a very nice pool when the disconnects and the 10%+ reject will be solved. Probably you will need and EU server, or some loadballancer. I will check back later.

hi trek


i been with the pool for nearly 6 days and never disconnected or went to my back up pool .....but today your pool has gone down ?is that to do with too many new users, putting a strain on your server ?

have you got a back up server address/pool ?

hope you can get this sorted......

We're getting bigger, faster, stronger. In the next couple of hours there will be another server up. Stay tuned and keep on mining.

Couldnt connect for the past hour. still cant connect. Whats happening?

So are you trying to say that the same settings we all use and have used for months/years on profit/coin switching pools don't apply to yours because you all are doing something beyond what the most venerable pools are doing in this space? I'm just trying to understand why the admins of the pool are doing this finger pointing the miners' way. I've never seen reject rates above 10% ever... but here it's like I'm giving away 25% of my hash power and not getting the results I expect from a 90% or better share efficiency.

I want to drink the koolaid guys, don't get me wrong. There's a LOT to like here; that said, pointing the finger at the miners and saying they are doing something wrong to experience this problem only with your pool sounds unreasonable.

That said, I will adjust my mining configs tonight a bit and see if it has any appreciate effect, but I would like to know, in a detailed technical explanation from the pool admin(s) why this is our issue and not a pool-side issue.

Thanks a bunch for the work...

I'm doing a log with the measurements of my gpu to find the best configuration for now lower the intensity as suggested several times by Terk really seems to work, please look here: https://docs.google.com/spreadsheets/d/1B-_UkIrGZYray8jb4K3Jnwx3JgweBHdaTCxgccgtFio/edit?usp=sharing
+1 for your question.

[Terk]

We’ve switched to a brand new server. Let me know if it improved your experience. I’m monitoring things from my side.

[_r2h]

Not usually one to remark about ~20min of graphs, but rejects tanked from 20 to 5%.  Coin swap or server swap, something doing well.   

[r00tdude]

We’ve switched to a brand new server. Let me know if it improved your experience. I’m monitoring things from my side.

And just like that, I'm now down around 5% the last time period since you added the new server without changing anything on my side... so can we just say that it's a capacity issue and let it go at that?

Thanks Terk for being so responsive... better for all of us, and you!

+1 for your question.

Thanks for the analysis - but I think we've gotten to the bottom of it given the additional server-side capacity addition and a marked drop in rejects since then. The last leg of the hashrate graph for me shows 5% rejects/stales which is really quite good. Looking forward to getting a full share at this point.

My rigs are still bouncing around between --failover and CM. Lets hope this gets settled quick as my rigs don't always bounce around pools all day and stay at 100%... Stability is the #1 goal, rejects are a distant second if profits well exceed LTC.

[evolvia31]

New server is ready and works
Because i have lots of disconnect and I switch every 5 minutes to backup pool.

[byt411]

Terk, I think you should have a "news" section on the site, and tell people about what is going on, since not everyone digs through all the pages on this thread.

[joshua3m]

I bet you will get a lot more action if you can add one server over here in Europe because rejects are killing most of us... 

[Terk]

We've been mining some very stable coins in recent minutes, so I don't expect the 1.4% rejected in the last 10 minutes to stay forever - it will be higher with different coins. But we've been having 6-8% with the same coins on the old server, so I guess it worked.

You might still experience occasional disconnects within the next hour or two as I'm tweaking some things, but your miners should be able to reconnect immediately.
