VrayRT production constantly crashing

V-Ray GPU V-Ray GPU :: Issues

Hi guys,

I have just started to render my images in high resolution (3000 pixels) and i have noticed VrayRT(production) is constantly crashing after a while when rendering the full image.
I use noise Max. Noise under Adaptive sampling.
If i render a small region, the render gets completed but not when i render the full image.

Here is the crash report. Any ideeas what could cause that ?

Problem signature:
Problem Event Name: APPCRASH

I’m using:

VrayRT 3.00.07
Windows Ultimate sp1

It would be great if you can get us the crashing scene to support@chaosgroup.com so that we can track this down and fix it.

Best regards,

Thanks for the help Vlado.
The scene is 71mb large so you will have to download it from our FTP.
I have send you an email with all the required details.

I have noticed that it crashes only when i use Noise Max under Adaptive Sampling.

Thank you very much for your update Peter,

We are downloading the scene file right now and will inform you as soon as we have any information.

Hi,

I just got the crash again and i can confirm it happens only when I use Noise Max.
Otherwise, without using Noise Max, it can render indefinitely and completely stable.

The error i’ve got is: Driver API error: 700
So this could very well be related to my drivers I suppose but I can confirm that all applications were clean installed(including the drivers) on a recently installed Windows.

Here’s the printscreen:

I couldn’t really find anything on google to my knowledge even though there are various issues regarding this error.
On CUDA developer website, they say:
CUDA_ERROR_LAUNCH_FAILED = 700
An exception occurred on the device while executing a kernel.
Common causes include dereferencing an invalid device pointer and accessing out of bounds shared memory.
The context cannot be used, so it must be destroyed (and a new one should be created).
All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.

No, it’s not a driver problem, it’s most likely an issue in our CUDA code that we need to fix.
