error:[MemoryManagerGpu::releaseUnmappedMemoryFromInstance]700:Could not release device buffer

[nicolas_fuminier]

There is a current Nvidia issue with these drivers causing memory leaks. Thread discussion here. Try reverting to 552 or 551 and see if there's a difference.



The antivirus false-positives issues were already addressed here. If the vdenoise.exe is still quarantined, try allowing the tool and see if the error persists.

Thanks for the fast answers, I was already following those threads in parallel.
For the memory leak, I though the memory leak was only in RTX mode, not in CUDA, but I might have wrong there. Since there is a strong security issue with the 552 & the 551, I might wait something something that combines safety and stability.
I also knew for the false positive, we tried to reinstall all our Vray with no new alert, but I might have check the quarantine log on every computer.

Best,
Nicolas

Pardon me, didn't notice you were using CUDA.

Otherwise, according to the article on this type of error, it might be a good idea to test-run a benchmark to see if it is indeed a V-Ray issue. Maybe the NVLink has something to do with it. Does rendering the scene in question yield issues on another workstation? If yes, do send the scene so we can take a look.

I'll try to switch for one of our work station with single 3090 see how it goes.
If I can't pin point it, i'll send you the scene (which is really very basic)
