Yep, that's the miner binary crashing for some reason. Impossible to know though because it's not open source so we cant run a debug version. Wrapping it in the shell script will reload it when it crashes so that segmentation fault would happen, but the application would restart right away.

Ok, I read though this thread again before posting this.  I was able to free up enough power on my other PSU to run two standard units.  After a few hours they stop mining, looks like a lot of people have this issue.  But I'm getting a message related to a segmentation fault in screen:  Command terminated with signal 11 (core file generated).   For the time being I wrapped my start script with crypto_curious's script from page 14, and they haven't stopped mining since.  However I dont think enough time has passed for me to consider this a good fix, we'll see.  Some people in this thread suggested the issue could be related to a bad connection to the internet, which is definitely possible in my situation.  I'll setup something to track that when I get back on site.  Im wondering if anyone else has seen the "Command terminated with signal 11 (core file generated)" message in the screen session running the miner software.  I am on Ubuntu 20.04 with an older kernel 5.4.0-58-generic (needed for issues related to GPU mining). 

My only other gripe is the miner output is extremely busy compared to other miners Im familiar with like trm and xmrig.  What stats should I keep an eye on?  Im sure I'll learn more as I get more familiar with this, but Im not really sure what is considered normal yet.  Thanks!

Emphasis mine.
Ja. One should NEVER try to run ANY sort of PSU's in parallel. Because they are independent devices they will literally fight each other. If you want to run PSU's in parallel they MUST be designed for it (master-slave modes) and wired accordingly.

Thats not a problem as long as you plug in both PCIE cables from the same PSU to the back of the Apollo, and the PSU has at least 200-300 watts headroom for the Apollo.

Issue come in when you try to plug in two separate power supplies in the back of the Apollo (ie some people think if they have 100 watt headroom in one PSU, and 200 watts in another, they'll just plug in one PCIE cable from each PSU to the back of the Apollo...THIS IS THE FIRE HAZARD). Even a small imbalance in voltage will cause major current to flow between the PSUs and melt the cables/start a fire.

Hi everyone!
I got mine.  Yeah!# 

I searched in the forum but did not get any suitable information about my question.
I have read that there can be fire Hazzard if you connect the Apollo miner incorrectly.
I got a Miner without PSU.

Can I connect the miner with a PSU that already supplies GPU-s during mining.
I have more than two x 6+2pin free and the PSU still has over 1000w power that is not needed, or is that a problem?
I'm not sure... 

Thank you for the Support.

Im trying to get zergpool setup with a standalone unit and I cant get the apollo miner software to accept zergpool pool options like -o and -a.  Anyone figure this out?

Im already frustrated the (aftermarket) psu I bought for 4 standalone units was doa, so I can only run 1 unit on leftover power from my other psu.    Irritating day.  

Edit-  needed to remove stratum+tcp:// from front of url, appears to be working now with options defined in apollo mining software (-host -pswd, etc)

edit2-  Forgot to say units look sharp and well made, nice job!  Very happy with this purchase.

I too have had the same issue happen multiple times with the some units randomly going inactive on dashboard and monitor giving a black screen with no signal after some period of time running. Reboot fixes both when one or both happens. Have flashed SD card no change. Happens on both old and new update version.

Hey everyone, support question.
Loving my miners, and they have generally been reliable, but recently had an issue.


Overnight, my miners seemingly went "offline" in that they were no longer accessible by the web-ui, and stopped sending hashes to my pool (0 reported speed).

However, the physical units themselves were still purring away, red LED and yellow LED's flashing, as well as the network port.
My router showed the device as online and identifiable as well.

I tried setting up with HDMI and keyboard but that seems to only work if they are already plugged in on boot.
So in this instance I got a black screen with no signal.


What should I do to safely shut these two units down other than pull the plug, knowing that the node seems to still be running?
Also, what in gods' name are those things 'hashing' if they are offline and sending out no data?

Thanks!

[UPDATE]
With it non-responsive and just wasting energy for the last 12 hours I went ahead and turned off the power supply.
Upon booting the units back up they are functional, but no-longer get any system info?

"There is a problem fetching system stats (Internal error)"
No CPU Temp, SSD storage space, or other hardware related info shows in the dashboard now.
Have re-booted multiple times since via software and the issue persists.  :'C

What is the username/password for SSH login to the node? Tried futurebit/futurebit (similar to the LTC appliance) but that does not work.

Thanks for so quick answer!

Well. Just couple of hours, but miner was restarted few times by me already and now I can see it just did restart itself.
But don't bother for now. I use Wifi and it's very laggy while block chain is downloaded. I'll wait for this to get completed and come back in case of any issues.

I think it gets more rejected shares just after miner startup.

BTW, my initial impression on this product is so good, so I just ordered standard box for this. Well done JStefano! Thank you for your work.

How long have you been running it? Id wait at least 24 hours before looking at pool stats, as it takes a while to stabilize especially if the pool is running high diff.

Hi all. I just got mine box yesterday. It's lovely ;-) It's quite a lot of pages in this thread already so just a quick question, sorry if it was discussed.

My miner is running in ECO mode at reported temperature of 60C. I get some rejected shares on CK pool. Miner is still downloading block chain...
It's about 5% of rejected shares, but both miner and CK pool reports 15-20% lower hash rate. Hardware error rate is about 0.4 -0.5%.

Is it normal?

Bitcoin Core 0.22 software released today

are you talking about the web dashboard? or the miner stops working?

Mine starts to run for a couple of days then stops and have to turn it off for awhile.
 
  Edit. 28th...currently running eco mode 51c
recently has been fine as the basement gets colder with less humidity. I just think it is sensitive to the basement even thought their were three fans on it.

Since the 0.3.1 build you don't need to remove the m.2 drive; that bug has been fixed
