DGX Spark GPU usage 0 after 24 Hours Open-WebUI

[DannyTup]

I confirmed that systemctl daemon-reload does lead to this issue for me, and that the workaround described does prevent it.

I added some more notes here:

"Failed to initialize NVML: Unknown Error" running nvidia-smi in a docker container only after some hours/days

Seems like the advice it gave is actually documented on the nvidia site here: So I will give this a go this evening. If it’s a known issue and the fix is clear, I’m not sure why it’s not just changed in the default OS setup though?

I would suggest trying this too, there’s a chance it will also resolve your issue.
