[ANN] [LTC] [PPS] [OTP 2FA] [Stratum only] LTCMine PPS mining pool (3.3%)

[Duetschpire]

all my miners also say they are down but keep on hashing and successfully submitting shares

Are you getting paid for the shares though? Last round I got next to nothing... from avg 0.082 to 0.002

[esenminer]

Same here - last round got next to nothing - the network difficulty was retargeted around the same time that the problems started for me - could it be related?

I'm not sure about it just being a front end issue because last round it recorded that i mined 1/10th of what i normally do even though the miners weren't reporting any difference. I can see the amount in my rewards list so it's storing and pulling that data from somewhere.

Not moving my miners for now, I'm sure they will figure it out.

I think the pool is still solving blocks, as there is about 1.5 MH/s unaccounted for right now: https://www.litecoinpool.org/pools

We'll probably get payouts when Balthazar wakes up and realizes the frontend is broken.  It also looks like the backend might be under DDoS as share submission appears to be slow.

[Balthazar]

Just woke up and seen received SMS.

Stats daemon crashed tonight.

I have a shares log, so that's not a problem, earnings will be recalculated today. Sorry for the inconvenience.

hooray for awesome admins

[Balthazar]

The reason of crash is funny, someone registered too many workers and submitted one share for each.

Fixed now, this should never happen again.

I'm so glad this happened... Since I started mining I started with this pool and always wanted to try other ones... Well, guess what? This pool is awesome!!! nowhere I am able to get 0.7% staling and 2 LTCs/day but here...

EXPERT OPINION NEEDED 

Its funny, I wake up and its strangely quite in the room  ..I switch on the screen but nothings pops up..Quick check on the laptop aaaand both workers are down  for few hours.
 It seems from the hashes as only one was working then 1/20th of one and then all stopped.. . Mining rig is idle - no screen but the cards fans were working at normal speed, very strange. Hard reset and hashing away, anyone have an idea what happened to my rig?

For me it's not uncommon, sometimes I find it recovered from an unexpected shutdown or just needs hard rebooting... Either the drivers would crash or a mem dump can occur. Remember computers aren't designed to be trashed the way we're treating them :-)

Once every now and then it ok, if it keep on happening you might wanna sit next to it for a couple of hours and see what exactly is going on... But if you're into troubleshooting on an event viewer level, you will find your answer there.

Thanks Deutschpire,

Its the first time I am seeing this behavior of "working" cards and sleeping and not responding system. Will keep and eye today

Just looked into the Event Viewer...

At round 1.08.00 am I have "a request to disable windows desktop manager" followed by "faulty application name cgminer.exe..module amdocl.dll" and to top things off   "amdkmdap driver crashed and successfully recovered" 1 sec after that...few hours later fragmentation process starts, finishes and the pc "shuts down ". Have in mind cards fans were working...Anyone

EDIT: One worker stopped soon after the upper mentioned findings the other 3 hours after that..

Received some emails... It seems that we have many users without email specified in profile, but they believe that the address was specified. It looks like they just forgot to do it.

I'll add warning on the main page, which will be displayed for users without email specified.

Done.

Later I'll perform the log analysis.

What should I do in order to keep reject ratio lower? I'm constantly getting about 3% which is quite a lot from what I read here...
Ping to ltcmine.ru from my miner is about 28-30ms which is really nice, so that shouldn't be a problem. What else can keep my reject ratio that high?

Which type of rejects do you get? Is it "unknown-work" or something another?

yes, unknown-work

There are two working sets - pool's working set and miner's local working set. The "unknown-work" message means that work doesn't exist in pool's working set anymore (or never existed). Pool working set cleanup procedure launched for every new block, received by pool from p2p network. Local working set cleared when miner receives "New work found" message from pool.

So, if miner got reject with "unknown-work" message, this means that local working set wasn't updated properly while pool's working set updated already. This could be caused by network problem, and can be resolved by manual expiry time decreasing. Try -E 30 option for cgminer/bfgminer.

P.S. Minimum shares difficulty border now is fixed at x64.

Thanks for the hint, I've applied it right now and will let you know if it helped :-)

[Dehumanizer]

Great, it looks like it helped a lot. Since I have changed the expiration, I'm getting almost no rejects at all, thanks again.
