Claymore rigs unhandled crushes

[kando45n]

Hello there!

Today all my rigs with claymore dual miner crushed.
Rigs have different versions of claymore, starting from 11.5 up to 11.9.

What happend:
In a hour approx all rigs stops, but, windows still running. Just miner software crush without any errors, watch dog does not help.
Windows updates fully disabled. I don't touch most of rigs more then half of year (and few more then year).
Also rigs stored in fully different places and don't have any relation

I don't see any helpful logs. Looks like it is just stop working. Windows logs also don't have any thing.

After restarting all rigs, I have few crushed again in a 2 hours after restart.

What happend? Anybody facing something equal???

Would you happen to be having Internet issues? All of them crashing at once sound like some type of connectivity problems. You can review your mining logs and/or router logs if you keep them.

Other suspects causes could be you are having slight electrical power fluctuations, not enough to shut off your miners completely but enough to crash the program. Could also be heat related, but this is less likely in the winter unless you live in the southern hemisphere..

You could even have a virus or some other malware on your network.

I should also add the in Winter with dryer air, which is likely if you are running many mining rigs, static electricity can become an issue. Just someone or something (pets) walking by a rig can be enough to cause it to crash.

3Gb cards? If so, welcome to the end of mining ETH on those cards )

[kando45n]

Thank you for so fast answers, but:

1) I have different places for rigs, so Internet connection also different (with different providers too)
2) Interesting idea about electricity, but again, it is 3 different places. But anyway I try check it (don't know, may be try call to electricity company)
3) I have thermometers in rooms, so temp statistic shows ~25C all time (I also have controllable coolers, they depends on thermometers)
4) Virus also good Idea, I try to check rigs with some antiviruses, but I think it is not related
5) I have 4Gb, 6Gb and 8Gb cards, so it is not related to end of epoch

I still researching logs and try found problems. At this moment all rigs online, but I think tomorrow I got few died

[Dzeronimo]

Are all those rigs connected to the same pool? Maybe pool had some problem that caused miner to crash. You can leave Claymore on some rigs and use another miner on the rest of rigs (use the same pool). If again only the rigs with Claymore crash you definitely have a problem with the miner.

Depending on your previous response, it looks like the only one left unchecked is the Operating System if all of your rigs uses the same.
Must be (still) a problem with Windows Update, it can still find a way to self-enable depending on your OS's version (especially Windows10).

Unfortunately, I can't help you with it since I'm not using W10 due to the same issue.

And...

Today all my rigs with claymore dual miner crushed.

It was beyond repair

DAG size became too large, you have to increase your virtual memory. The size of the swap file must be more than sum of all memory of your GPUs.

[kando45n]

Guys, thank you for all again!

But I try check all described things. It is really looks like magic.

More important! Today my friend told me same story. He have some less rig count, and all they crush like my.
But he say about some logs and promise me send it later, so I waiting for review and post it.

Also I enable logs in few my rigs, but I have new crushes in another rigs So I need some time for enable logs in all rigs for find problem.

I post back when get any information

Hello there!

So in most of rigs I have many many rows in logs like this part:

So after this logs program just crush

[Dzeronimo]

You are not the only one with that issue. This post is two years old https://bitcointalk.org/index.php?topic=1670733.msg17167363#msg17167363 so it's not a new issue. Try to ask for help in the official Claymore thread.

[irman.truman]

I facing same issue two days ago.

It looks very equal to Dzeronimo's answer but now. It is different problem and I don't find same in Claymore thread.
I still try to google it and check all my rigs/internet/electricity and now I can say, it is problem with Claymore it self.
May be virus, but it working from network, not from local OS

Hie,

I have the same problem too... windows is running good but miner crashes and all other mining programs are working except claymore 11.X. i have tried all claymore versions, i have checked all other ways. please help me in finding solution.my virtual memory is 50GB. i have tried phoenix miner, it is good

[Bokile]

I've just checked and saw that latest Claymore miner is over a year old https://mega.nz/#F!P0ZjFDjC!Cmb-ZRqlbAnNrajRtp4zvA. Maybe it has some compatibility issue with the latest Windows build. You guys should try some other miner.

[VasilyS]

I'm using 11.5 and 11.9 versions of Claymore for Ethereum. They are working very stable and give approximately the same hashrate as latest Phoenix miner. I think that problems appear if there are very strong overclocking and small size of the swap file.

[kando45n]

Looks like I found solution.
Few days I use this patch in 6 rigs (in different places)

https://github.com/proxymanext/claymore-srv-fix

At this moment crushed end's. Hash rate stable and same to original claymore.
Today I try update other rigs to this version, hope it help to me.

[Bokile]

I'm glad you solved your problem, but is this solution safe? This is unofficial fix, right? Are you sure that code is virus-free?

[kando45n]

Thank you for your worry. Of cause I can't be sure about safe. But in last 6 days approx I don't see any changes in hashrate all work stable and like original Claymore. So I leave it as is and if something happened later I leave a message here

I'm not worried about the hash rate and small % that miner can take. I'm afraid of key loggers that can help hackers to steal all you have in wallets, exchanges...

I'm pretty sure that any clever miners wont use his mining rigs as a (spendable) wallet.
If there's a real threat, it will be his privacy.

unless if there's something in the code/file.

[Bokile]

Some people mine on their desktop PC, the only computer they have, so they don't have much choice. No one can guarantee that malware isn't inserted in this modified miner's code.
