Information for sellers/providers: We have extended cgminer with extranonce.subscribe feature (no disconnects - better efficiency). Sources for the patch are available in our GIT repository. You are welcome to ask manufacturers of your ASIC miners to include extranonoce.subscribe patch from our GIT repository and provide updated cgminer binaries or firmwares with extranonoce.subscribe subscription. This feature is optional and can be enabled by adding "#xnsub" at the end of the pool URI: stratum+tcp://stratum.nicehash.com:3334#xnsub You can also download pre-compiled binaries for AntMiner S1 and AntMiner S3 with cgminer 4.7 and extranonoce.subscribe patch and replace stock AntMiner cgminer binary to benefit from extranonce.subscribe for better efficiency: AntMinerS1-cgminer.zip (MD5 checksum: 5983572e753ee2f7af18da098f1d01a2), binary provided by 7queue AntMinerS3-cgminer.zip (MD5 checksum: f980b534b8ee2c71f81e2395533a3f4f), binary provided by ckolivas Instructions how to replace stock AntMiner cgminer binary are included in the zip packages as README file. Examples of working Extranonce subscription: AntMiner S1: https://www.westhash.com/index.jsp?p=miners&a=1&d=1&addr=1B4RkonuDVkGzKSTe4MCfZfSHseMGyump2AntMiner S3: https://www.nicehash.com/index.jsp?p=miners&a=1&d=1&addr=15r3JQvW73FbphxjPN2oLGeQQyEXhhZLdrMore info here: https://www.nicehash.com/software/#cgminer

My miner has shown all the autoswitch repos as dead since yesterday. Here's my config:
f0=0;f2=0.55;f3=12.5;f4=9.2;f5=960;f6=8;f7=42.5;f8=0.65;c0=0.0;c2=1.25;c3=0.94;c4=0.92;c5=1.27;c6=0.92;c7=1.06;c8=1.02
What gives?

This feature is optional and can be enabled by adding "#xnsub" at the end of the pool URI: stratum+tcp://stratum.nicehash.com#xnsub
Clarification: on an Ant the "#xnsub" goes after the port in the URI. So it would be stratum+tcp://stratum.nicehash.com:3334#xnsub I did this and my S3's are running like raped apes. Nice improvement, thanks!

nicehash.. so you do not want to comment on this? what's going on on buyer's side? ( scrypt, last two days, mainly on nicehash, not westhash )
there is one bot which places one order for every amount ( 0.23 , 0.24 , 0.25 . 0.26 etc .. ). he always uses a limit of ca 10-13 ghash.. then he sets the limit for high prices to 0.1 ghash.. so he always gets the cheapest hashrate.. if a place an order, i am always overbidden automatially within seconds.. he always invests a maximum of 0.05 btc or so.. and refills it once a minute or so.. as these orders stay for 15 days, he is always the top bidder for every amount... come on nicehash, this can not be allowed! pleace introduce higher fees for bids / introduce fees for refilling / set an order down in the queue if refilled!
addionally: during the day often 75% of the scrypt bids get dead simultaneously.. so the price drops to 0.07 or so ( much under value, ltc = 0.22 ) all my pools still work on westhash, but the very same pools on nicehash are shown as "dead" BUT: the orders of this creepy bot stay active that can't be a coincidence! he gets hashrate for 0.07 and i am dead!
so it would be nice, if nicehash would comment on this..
( proof: please check order #122027, #122151 , #122024 , #122149 , #122148, #122022, #122767 , #122020 , #122766 , #122019 , #122010 , #122009 , #112716 , #121358 , #122008 , #121357 )
actual problem: my bids get inactive..on nicehash and westhash.. the other bids not.. why? i have around 10 jobs.. i create them manueally over the website! so no flood on my side.. http://picload.org/image/coorigi/2014-11-2312_06_40-westhash.pngand suddenly after my 0.22 order is "dead" , the price falls from 0.23 to 0.19 and this bot gets all the cheap hashrate.. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs14.directupload.net%2Fimages%2F141123%2Fdnhqyubl.png&t=665&c=GQAyxTH0ImxG6Q) this is bad for me, the miners get less payout and you get less fees. this is really annoying! so why is this happening?

Job flood means that remote pool flooded our stratum proxy with too many jobs in short period of time. Avoid using such pools and use legit pools that do not perform malicious activity or reduce miners performances.

okay thank you for that information..
and the other pont is okay..? that there is a very aggresive bot who places/ changes multiple orders every second? consequence would be that i write my own bot.. then the next people write bots.. so it is going to be very hard for the typical user to use your website from the web interface..

Is there anything wrong with westhash? My hash rate went down about 50% and it is not stable in the last 2-3 days, went off for a while yesterday, a couple of hours. Had nicehash set as a secondary pool and that failed.. Nothing wrong with the devices as they work well on multipool.us. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FGnDH8v0.png&t=665&c=7tHERXNZAS846w)

The one I set has no problem. Details please: - Hardware
- Miner - software
- configuration
Maybe, enabling Extranonce will increase the hash-rate. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ~~MZ~~

I unplugged all of the miners and let them sit for a while and everything is back to normal. Thanks for reply and help.

To mitigate these issues we added another rule in orders sorting: 4th Rule: Changing limit hashing speed to lower value resets your position to the bottom of sub-list of same-priced orders. This rule penalizes low-limit place-holder orders. https://www.nicehash.com/index.jsp?p=faq#faqb1
