Sometime today mmpool went down or got DDOS attacked or something, bad gateway error in nginx trying to view my account.

Whenever I try to start my Saturn mining, it says Halted (Check Miner Settings).

I have checked my miner settings, I checked they still say the same connect info for mmpool.

But it just keeps saying it halted.

It had not said that when I first found out mmpool was down. It just had crazy-low temperature for its purported mining speed.

I added my p2pool as a second pool, but p2pool is broken nowadays it seems (endless cries of too many open files), so I removed p2pool leaving only mmpool and got this halted thing. So I deleted that too, reset to factory settings, and input mmpool again.

Still get this damn halted thing.

Looked at the manual edit, the syntax looks fine.

Reloaded 0.99 firmware and rebooted. Still the same error.

What is going on?

EDIT: Power-cycling the thing fixed it.

If u use the dsl modem just turn him off and on with new dynamics IP it will solve the issue

[Madazam]

not enough power?

If answer to my comment than i am using Lepa 16000 and kikkawatt shows barely 600 watts being used ....

[demonmaestro]

is it still hashing?
Have you tried another fan?

Trouble shooting wise.

Make sure all the power cables are correctly attached.
Do a hard reset on the device:

The cables are correctly attached (powering down wouldn't have changed them in any case)

I did a hard reset then ran through all the various firmwares before I posted.

Lastly, If you can isolate the bad board, then you can just return that bad board for an RMA and the miner can continue mining, you don't have to lose the entire miner and 480Gh/s just for one bad board.

I have isolated the bad board.  Being able to RMA a single board changes things somewhat.  I will probably do that after the next difficulty increase.

Looks good, but every hardware is different with respect to dud cores. Some is golden and some is scat.

ck, can you elaborate a little on the difference in behaviour & reporting between the 3.8.2 tuned and non-tuned on a KnC miner?

Reporting between the two is identical.

The tuned one simply changes the decision making process about when to turn a core off and back on. Firstly it turns all cores on every time it's starting. However it turns cores off very quickly instead of after many errors, but turns cores off in a staggered fashion a few seconds apart. Then it turns them back on after only a minute, but will only turn cores back on if no core on/off has happened for the last minute staggering them much more to turn them back on. My observations were that turning dud cores off always helps the hashrate so making it easier to turn cores off made sense, but with rapid changes to the number of cores on/off, the power going to the units changes wildly when in fact the device will be more stable if it only ever changes power requirements slowly, hence the changes. It also increases the duration cores are off every time they fail before disabling them permanently (for that run of cgminer).

Anyway I find the hashrate and consequently the hardware error rate keeps improving over time as only the decent cores are left hashing, and cores that are borderline turn on and off intermittently in a staggered way that doesn't change the power requirements dramatically.

So with 3.8.2 non-tuned my HW error rate is like 1.5% when I was running the older tuned version it was enabling and disabling cores all the time and I had a HW error rate closer to 5%

Non tuned doesn't disable the cores, but tuned does if they return X number of errors. So with non tuned its just getting errors back from the "bad" cores, but the error rate would seem to refute that.

Sorry, just trying to get my head around it. Logically I would think that my Jupiter has the same amount of cores giving out errors regardless of the software used.

I'll leave non-tuned running for another day, output seems stable after 24 hours, but I'm still interested to see if the tuned version will make any difference to both the HW and overall avg output.

Thanks

Now the problem.  I shut the full speed unit down for a few minutes to change locations and when I restarted it cgminer fails to start.  The bone boots and I can tty into it.  I can try to manually start cgminer and I get a "cgminer failed to start: Write Error".

I'm not able to find the string 'Write Error' (without caps as well) in cgminer source code.
Is it the exact error msg you get ?

The error seems to have been thrown by /etc/init.d/cgminer.sh
I can't seem to reproduce it right now.  Instead I am getting "-sh: etc/init.d/cgminer: not found"  however "less /etc/init.d/cgminer.sh" gives:

If so I guess your issue is located somewhere in the OS.
Anything useful in the log file ?

*Note: journalctl is the replacement for a "less /var/log/syslog"
http://www.freedesktop.org/software/systemd/man/journalctl.html

I have not gotten a result from journalctl.  Probably because it is not in the path and I don't know where to find it.

I haven't messed with a Unix system for 30 years so I am a little rusty.  :-)  I would be more at home in JCL.  I guess in the morning I will have to go find a good Linux book.

TaggedYa,

I'm wondering whether you removed the first line from the cgminer.sh ?

Your quoted script is missing

Code:

#!/bin/sh

concerning the log file, It was an educated guess - sorry It did not help
you could search for the log-file location with

Code:

find / -regex 'syslog|messages'

No mines the same. OK so its not out of space. Its just wierd that it boots but cgminer won't run.

bless u biffa. i KNOW when im being a dick, and its usually intentional...

i agree phoenix HAS made some great contributions, but hes also made some absolutely shit ones and seems to not know the difference nor appreciate constructive criticism.

anyway, now hes given it a rest the thread can continue to provide much needed & appreciated support.

thx again and ill try & tone it down a touch.

i considered removing the blue extensions but so far im leaving it at 529Gh - i'll maybe have another fiddle when he Nov shipment arrives.

Dont wanna make it worse until i have some backup hashing power

strange.

since there're a lot of things going on when you issue a cgminer.sh start and a lot of those are related with the initialization of the asic boards I'm afraid that there's something wrong going on in this phase.
this are all the tasks performed:

Code:

root@lucas:~# fgrep \# /etc/init.d/cgminer.sh 
#!/bin/sh
        # Stop SPI poller
        # CLear faults in megadlynx's
                        # Re-enable PLL
                        # re-enable all cores
                        # Disable PLL
                        # disable all cores
        # Disable direct SPI
        # Enable SPI poller

all of them involved some sort of i2cset command executions.

If I were you I would join #kncminer channel on freenode and try to ask hno (an OrSoC eng) if he have an idea of what's going on.

i am testing right now cgminer-tune with my jupiter that has got some problems at the beginning and is mining at 520GH with 3.8.1. i can report that the jupiter is hashing now at 480GH . and i am not sure but it takes some time till the working diff has changed usually i think it got changed faster. i am mining on eligius btw.

i will update you in 2-3h.

edit:
after one hour it is working at 511GH/s

I have been trying to figure out why two of my boards (one new, one old) from upgrading my Saturn now are reporting dead dies 0-3 with no output wattage for the two boards. Running enablecores hasn't changed anything, and firmware 0.98.1 didnt work and neither did the older firmwares. They both don't hash on any port now and I'm running a XFX Black Edition 1050W with a Seasonic 1250W Gold coming in later today. My bertmod output with the two dead boards are below:

Heads-up for tomo BTW - incoming...

is this kind of post considered useful?


why not be a tad less 'cryptic' and you(r inbox) might not get abused so much...


Also want to add, my ambient temps are 30C - 86F.

 so statements regarding VRMs needing heating and/or not liking cooling is NOT a fact covering ALL rigs/VRMs and even when they are hot(ter) they dont ALL fall back into line....

im sure ive mentioned this...

As for 'wiggling' the heatsink aka 'cooling tower' - i think ill give that a miss.

i personally dont want to hear 'warranty' is void due to negligence/abuse/possibly insane advice (though it might just work)

Nobody said the temp issue covered "All rigs", and you still don't get what sharing info is about helping others in need, who ARE having problems.... and if you cared to read just a few posts more, before bashing O'rama, you would have seen that he spelled it out for those who can't "Read between the lines", but you still even missed it.
What is your problem? Someone piss in your Cornflakes?
I also stated clocking the heat-sink was a desperation move on my part, and that the temp thing was NOT a recommendation.
It was a question!!!
But.. it has helped others.
There are two options when you have a board that isn't performing up to spec as I see it..... RMA it, or try to get it going yourself.
Which one you try, is up to the owner...
I'm an "Open book" in here, which is something I'm not used to...  but if I can help someone, by golly..I'll do it....and share every conventional AND unconventional solutions I find. It is then up to you as the fellow KNC miner owner to make a decision based on how you feel about it.
You would rather see everyone with a simple glitch on board do an RMA when they could possibly be fixed so simply?
Not me... 

The temp issue is confusing.  ASICs will have increased errors as heat increases since impurities will cause triggering of gates at random causing illogical conditions which themselves can cause more heat.  If VRMs are running better hot than cool then I would think something is wrong, e.g. some open that closes with expansion due to heat, otherwise I don't see how heat can improve operation.

I am not sure this is the right place for this but this seems to be a catch all thread so here goes.

I have 2 late October Jupiters.  One I was able to get to 550 with all cores running under 98.1 beta.  The other has 2 cores on one board that will not work until 73C or 74C and as soon as they start the whole board shuts down (I assume thermal shutdown) so it only works at around 480.

I was living with that (not economically feasible to give up 480 hashes for 2 weeks to rma the thing just to maybe get another 60 or so).

Now the problem.  I shut the full speed unit down for a few minutes to change locations and when I restarted it cgminer fails to start.  The bone boots and I can tty into it.  I can try to manually start cgminer and I get a "cgminer failed to start: Write Error".

I tried changing firmware.  Cgminer will run on 98 but not on anything after and on 98 I have all die 0s dead.

Anyone have any clues?

Put a voltmeter on your power supplys and check you have ~5v and ~12v.  Also, I found my 4 pin molex could have been a little loose on the pins and closed the "tubes" a bit to fit more snugly on the board mounted 4 pin molex pins.
