CUDA error

[dhanad]

ERROR | [gpu] an error happened during rendering : Unknown error (Details: Function "_rtContextLaunch2D" caught exception: Encountered a CUDA error: cudaDriver().CuEventSynchronize( m_event ) returned (700): Illegal address, file: <internal>, line: 0)

I am not seeing this error in other scenes (yet), maybe because they are not as complex. But I keep getting this error in this one project I am currently working on. Is it possible that scene has something that is generating this error. It occurs everytime I import a mesh into the scene. I do a cleanup of unused nodes using Hypergraph connection, and Optimize scene. That helped in one occasion. Now I imported another mesh (obj), and same thing. Same error. I am attaching the Debug log file.

I am using Maya 2020.2, with the latest Arnold MtoA, and Nvidia Studio 451.48.

Can you try with the recommended driver?

451.77 or higher on Windows

Ok, gonna try that now. After I update, should I delete the old pre-populated cache manually before redoing the pre-populate cache for the new driver? Or just leave the old one there.

Updating the driver didn't help =( Something in my scene is causing this perhaps, trying to isolate what that is. Beginning to think if I should start a clean scene and import my meshes and shader network. I just hope it's not a out of memory issue. I have a pair of Titan RTX NVlinked. And if I am reading the output log correctly it's not going over 10-12gb. I could be wrong though.
