WATCHDOG: GPU 4 hangs in OpenCL call, exit ... need to restart ...

[daryong]

Hi,

I am trying to mining 12 gpu from ubuntu. With 8 gpu, the window 10 has already been successfully mined.

However, when i try to mine in ubuntu, i will get an error such as GPU hangs randomly. Claymore wisely restarts the program at this time. However, every time there is a decrease in gpu memory and eventually a DAG alloc error It can no longer be mined.

In Windows, Claymore did not go down, so when I looked up the log, Windows sometimes restarted the program. But I found a difference with Linux.

< Claymore Restart Log - Windows > 17:59:47:926 f80 WATCHDOG: GPU 4 hangs in OpenCL call, exit 17:59:47:942 f80 watchdog - thread 10 (gpu5), hb time 297 17:59:47:957 f80 watchdog - thread 11 (gpu5), hb time 156 17:59:47:957 f80 watchdog - thread 12 (gpu6), hb time 296 17:59:47:973 f80 watchdog - thread 13 (gpu6), hb time 172 17:59:47:988 f80 watchdog - thread 14 (gpu7), hb time 219 17:59:48:004 f80 watchdog - thread 15 (gpu7), hb time 78 17:59:48:254 f80 OC v7, Reset control for GPU 0, close miner right now if you want to use default control from Catalyst 17:59:48:270 f80 OC v7, Reset control for GPU 1, close miner right now if you want to use default control from Catalyst 17:59:48:270 f80 OC v7, Reset control for GPU 2, close miner right now if you want to use default control from Catalyst 17:59:48:270 f80 OC v7, Reset control for GPU 3, close miner right now if you want to use default control from Catalyst 17:59:48:442 f80 OC v7, Reset control for GPU 4, close miner right now if you want to use default control from Catalyst 17:59:48:442 f80 OC v7, Reset control for GPU 5, close miner right now if you want to use default control from Catalyst 17:59:48:457 f80 OC v7, Reset control for GPU 6, close miner right now if you want to use default control from Catalyst 17:59:48:457 f80 OC v7, Reset control for GPU 7, close miner right now if you want to use default control from Catalyst 17:59:49:583 f80 Restarting OK, exit...

In other words, there seems to be no gpu reset process on linux. So, in linux, restarting seems to be abnormal.

At present, ubuntu installs only amdgpu-pro-17.40 and runs claymore.

Claymore's bug? Is this happening because there are libraries that are not installed? ( For example, AMD_APP_SDK or ADL_SDK ... )

Thank you.

I am also facing the same issue on Windows 10...Can any please help.

Thanks!

can anyone help on this

Well, i didn't try this on ubuntu, but from my experience, this usually happens when you overclocked your cards to much. Try to reduce overclock / under-voltage a bit. Another solution that can be helpfull - turn off claymore's watchdog. A friend of mine didn't want to reduce overclock so he disabled watchdog and that helped him :)

You can do that like this: -wd 0

I suffer in that too, changing PEG1 to gen2 and PEG0 to gen3 from auto plus increasing pci latency seem to 64 helped a bit. Also i removed all the rubber protectives from the io-ports.

Not sure if this will help anyone but after almost 1 month Of having the same issue, my problem turned out to be with PSU. On my previous rigs I used Corsair RM1200 PSU's but on the new one I have HX1200 which has a switch on the back between single and multiple. It was set on multiple and after an hour or sometimes even 2 minutes a random card would fail. Since I see itched it to single my rig has now been working for over 3 days without any issues what so ever. According to Corsair if the switch is in 'multiple' position each connector has Over Current Protection so if there is current surge in your outlet it will limit the power hence why a GPU would not get enough power and stop working. Try it and let me know if it solves the problem.

I actually had 2 broken cards under warranty, removing those helped.

Passed some time but lately I had the same problem with one of my rigs so I went checking from software to hardware and it come up as faulty riser.

Hello,

----- watchdog gpu 0 hangs in opencl call exit ----------------

I'm encountering one issue, while mining from "https://ethermine.org". I'm using ethdcrminer64.exe for mining with Nvidia card, but after few minutes it got stuck and never come back until I quit the miner and start again. Please guide me on that. I also attach one file, for reference please find the attachment. Thanks
