Ok... I'll try to explain this problem again and hopefully someone else has experience and can help me.

Problem #1:  11 GS miners hashing power degrading and not maintaining advertised hash rates.  This is a  problem on 3 sites currently.  I continue to see the hash rate degrade on MP, IPOM and CM.  It does not matter the coin or site.  GS's supposedly should run at 0.333MH/s but mine are degrading over time until all 11 are at 0.27MH/s.   

  Suggestions I have tried but will not work... MP suggested setting share difficulty to 64.  Tried but no improvement observed.
                                                                 Mine on equip set for mining only.  Rasp Pi is dedicated 100% to GS mining. i.e. suggestion no help!
                                                                 
Problem #2:  Eventually, all 11 miners will shutdown... MinePeon shows no miners active even though miners are still running?  Failover fails (no pun) and backup pools never activated even though software is set and supposedly is capable of restarting on backup?


Here are my settings from MinePeon.... Please if anyone has success running GS's with minepeon and can give me some real help, please contact me.

#!/bin/bash
sleep 10
/usr/bin/screen -dmS miner /opt/minepeon/bin/bfgminer -S all -c /opt/minepeon/etc/miner.conf --scrypt --set-device gridseed:clock=805
 
Ok just had GS's shutdown (no hash) when multipool switched to new coin?

[Catswold]

That was a short ride.  Profitability is back down almost to DOGE levels, .00625/mh vs. .00617/mh.

Of course DOGE varies with each block as difficulty cycles; just dropped to 0054.

[PCMiner]

Yes my miners have been slowly losing hash rate until they shut down completely on CM.  So I switched to ipominer, CINNI and they had problems with cinni servers and again my miners shutdown, but never switched to backup.  So down all day.   Ahhhhhhhhhhhhhhh.

So I switched back to CM and gridseeds shutdown again.   Not sure what is going on?

I had a day when all my gridseeds shut down at once.  I did "this and that" and they finally started up.
I left the house, came back.  Again they all shut down.

Long story short, I finally concluded that plugging my phone into a port on the front of the computer that runs my mining software was what caused it.

Pardon me for not qualifying what "this and that" includes,  nor detailing what mining software I am using and etc.  I tied a knot in the cable that I was using to charge my phone so I would recognize it and never use it again (but I kept it in case I wanted to prove it was the culprit).

...I use a USB mapping utility called UsbTreeView, and on its diagram the port where my phone was plugged in, it showed a yellow "i" indicating a problem. 

I am not suggesting that your telephone is causing your problem, but rather I am encouraging you to maybe look elsewhere besides the gridseeds and power supply, as I had to do.

A prime example of what we techie people hate.  You try everything under the sun to get something working again, and it winds up being the thing that can't possibly have anything to do with it.

Isn't 805 an odd frequency? Did you mean 850?

BTW, there seems to be some anecdotal evidence that GridSeeds are happier with frequency values that are an even multiple of 25. Since moving my GSDs to frequencies like that, I've seen more predicable performance.

I have noticed that on this pool there is a long delay, several hours usually, before mined coins are exchanged for bitcoins.
My question is: doesn't this undermine the very concept of multi-coin mining, i.e. mining the coins that are most profitable in that moment? If you wait several hours before trading at the exchange don't you risk to lose profitability (or to take a loss)?

Coins have to mature and be sent to exchanges.
Also, coins are usually profitable due to a difficulty drop, not due to a price spike.

Site down for anyone else? Went to check my stuff at lunch and says site it down.

http://www.clevermining.com/users/11tK3hF4KN9t2kZbRgqdafdcNMDyPW2ru

I apologize in advanced if someone has answered this recently. I only have 15 mins for lunch so not enough time to filter through th previous pages atm.

Thanks

[Xenocyde]

Site is back up. Cloudflare does some 15-20 minutes maintenance from time to time.

[BCata]

No good ideas, but having the same issue.  In trying 800 MHz and 900MHz each separately for about 24 hours, I received even lower hash rates on CM.

I'm running 20 Gridseeds, RaPi, and CGMiner 3.7.2 showing ~7.2Mh/s on miner, but only showing up ~5.0Mh/s on CM.  That puts each GS averaging about 250 Kh/s on CM, but showing 360 Kh/s on CGMiner.  My GS have fairly equal accepted work, are mining pretty efficiently at 850 MHz, with minimal (0-3) HW errors per unit per 24 hours.  Reject rate is just over 1%.

I'd too would like comments back if others are experiencing lower hash rates on CM and any tweeks or adjustments to increase real, recognized hash rates on CM.  Hey - not complaining though - with the recent ~200% returns, it was like getting real 500 KH/s from each GS! 

Thanks for a great pool and the professional efforts/information from everyone!

I have the same issue, but it is only a recent issue (it was not present last week). I tried several other sites and the problem only appears on CM. CGminer show 10.8 MH/s, on WP I get around 10.5 average, on other pools well over 10. On CM I get a bit over 8 on average. So about 85% of my hash rate. Rejects are really low, 1-1.5%.

Hey, I hear you.

Let me say that I worked as an electronics technician for 17 years, and no matter how smart you are about diagnosing, you are also lucky any time you get it right.  (Like putting in golf...)

I control some lights in my house using X10 controllers.  Lightning struck a tree outside my house.  Afterwards, I could remotely turn the kitchen light off (which is what I always want to do), but I could not turn it on.  I replaced the switch module, and the receiver, and used a different hand unit.  Tried different house and device codes, no joy.  The one night, suddenly, the light turned ITSELF on!  I tried my hand unit right away, and sure enough, I could now turn the light on, and I could turn it off.  But it continues to turn itself on from time to time, several times a day.

so I may have missed this in the many pages here, but have we ever gotten an API?

The whole cloudflare/ddos protection stuff is nice to keep the pool up, but incredibly annoying for both checking hte pages and trying to write data scrapers to track my performance.

If there is no API (still) any one have any suggestions on how to scrape data from their miner pages?  I cant seem to get around the cloudflare junk

I am having the same problem in trying to "data scrape" as you call it.  I read on the CloudFlare site that their protection does not prevent web crawlers from scanning the site (so I am confident we can find a way to do it), and I'm thinking what I will try next is to write code to accept their cookie(s).  Of course, my guess is worthless until I have it running.

What I unsuccessfully tried in php was to file_get_contents, then do a javascript setTimeout of 10 seconds, after which I do a window.location.reload.  

hmmm, well i guess if they say web crawlers can scan it, there has to be a way. what's the link where you read this?

I went the python route a few weeks back, but got no where.  After reading your post, i fired wireshark back up and it looks like there's a hidden form that needs some special key to return in order to let us through ... so I also think we'll need some code to accept their cookie/whatever and respond back similar to how a browser would.  still kind of pain to grab some data  

update: ok so i did some digging. got this from the cloudflare site:
Javascript and cookies are required for the tests, and to record the fact that the tests were correctly passed. The page which your visitors see when in IUAM can be fully customized to reflect your branding. I'm Under Attack mode does not block search engine crawlers or your existing CloudFlare whitelist.

My guess is they whitelisted known and allowed search engine crawlers which is why those bots work where as ours dont.  Add to it that it looks like Terk opted to put the domain in a permanent I'm Under Attack Mode and we are where we are. So pretty much we need to mimic the expected behavior if we want anything to work ... lovely

I neednt link you now, your text is exactly what I read.  I did not reach the conclusion that you did about the crawlers being whitelisted, thanks for helping me think! 

As to "kind of a pain", well, it would be worth it so I could get some sleep, I'm plain stupid about having to check every hour and enter data into a spreadsheet.  Auto-reading from CM is the only missing link.  I'm databasing the exchange rates of 5 different coins once every five minutes, making graphs, all automatically.

[lk_qwerty]

based on a rough calculation it looks like there is about a 2-3% drag due to significantly aged unexchanged balances. do these ever work their way out, or should profitability be viewed from the perspective that not all balances will eventually be realized?

Sure they do, I've been mining at clevermining for a while and it's the best I've seen. I figure that this is caused by the huge hashrate and of course the huge volume, the volume of alts generated on a daily basis has to be incredible which is what shows how well this pool is, handling such a king sized volume of coins has to be quite challenging.

what is a reasonable time frame to expect? i was only looking at those older than 2 weeks, and there is a fair amount older than a month.

The first one is from CleverMining, the second one from WafflePool (or maybe it's the other way around). Great minds think alike?

The pool marks coins as exchanged after they are withdrawn from exchanges plus three confirmations. Actual exchanging into BTC is done much earlier and is ongoing. Withdrawing is done few times per day and at this moment balances are marked as exchanged.

See https://github.com/jordoh/miner-monitor/blob/master/pools/clever_mining.rb#L84-L102 for ruby code. The basic process is:

1. Get the 503 page from CloudFlare - it contains a verification code (in the HTML) and simple equation to solve (in the JS).
2. Make a get request for http://www.clevermining.com/cdn-cgi/l/chk_jschl?jschl_vc=<verification code from step 1>&jschl_answer=<answer to equation from step 1> with the referer header set to the page you are trying to access. If you got the answer right, you'll a 302 (redirect) response with a cf_clearance cookie.
3. Follow the redirect (i.e. request the original page you were trying to access), including the cf_clearance cookie.
