Rigs Disconnects from Network (Asrock H110 Btc+)

  • Hi, same problem here. I know it is caused by the Asrock H110 Btc+ motherboard because it is flooding the network in some way. If I switch of the miner with this motherboard al of my other miners with PimpOs (and a different type of motherboard, are coming directly back online. After switching of this miner and a reboot everything works fine for aproximately 46 - 60 hours. In my case It is not an ISP issue.

    (There are more reports on this issue i.e.: https://github.com/nanopool/ewbf-miner/issues/67, do a Google search with Asrock H110 Btc+ network flooding)

    At this moment I am figuring out what causes it. An update to the latest Bios version (version 1.6) does not fix the issue for me. I'll keep you posted.

    This might be an obvious question, but let me ask it anyway... You do have a paid subscription to miner.farm, right?

    Hello Doc,

    No you can use miner.farm for free for up to 2 miners. For more then 2 miners, or for extra features then their are 3 additional paid for plans, which you can view here: https://miner.farm/#features

    Hope this helps,
    Best Louis

    That's my point. He's showing 5 rigs. If he doesn't have a paid subscription for 5 (or more) miners and loads all 5 rigs with his API keys (short & long), then miner.farm will randomly start dropping and upping rigs.

    I know this, because I made the mistake of adding my 3rd rig to my 2 miner limited miner.farm account. The rigs mined just fine, it was miner.farm that didn't like more than my 2 rig limited account.

  • I have a paid subscription for 15 miners (using 6 at this moment).

    Anyone have any luck with getting this sorted out?

    If you did, please post what you did to fix it for other Pimps that might be suffering the same problem. Thanks.

  • The problem ocurred again after aprox 4 days. I am using Bminer. After several restarts of the miner (not the rig and not the agent), with a shortening interval first 1 day and then approx 4 hours and then 2 hours Bminer stops and rig totally 'freezes' failing to reboot. Then the network problem occurs. Al other mining rigs aren't able to connect to the mining pools (and miner farm). Only shutdown of the power of the rig causing the problems, makes the other rigs directly connect to the pools (and miner farm). The rig causing the problems has 12 GPU in it. (On the internet there are several reports that this prblem occurs when having more than 6 GPUś on the Asrock H110 Btc+. The mining rigs has an IP4 and IP6 ip-address assigned by the router.

    No solution yet.

  • I'm wondering if this is my issue as well. It says my miner has disconnected from the network but in my case it is still mining on the pool. I cant get and logs off the miner itself either. I have this same exact board. This rig was running strong for 2 months. No reboots or restarts. A solid 2 months of mining. What could have changed?

  • [/root]:# pimp --test 1
    Preparing to test mining on Miner ID 1...
    Another miner is running on port 4028 - not starting.

    [/root]:# pimp --list

    But, it is mining...

  • Could an external nic fix this issue ?

  • Staff

    If you can, this would be an excellent troubleshooting step, @devinmosher. Try disabling the onboard NIC in the BIOS of the motherboard (aka UEFI setup) and use a PCI or USB NIC and see if that changes the behavior. Perhaps it's something with the way H110 did things with their bus, and this can help find out.

  • I am having the same issue, has anyone resolved this? Has using an external NIC been successful?

  • Staff

    Yes, external nic or using a Layer3 switch will work until we develop a more robust fix. Thanks!
