Maya 2022.3 with mtoa 5.0.0.2 and Arnold Core 7.0.0.1 is crashing due to and OpenGL driver error. Error code:6
also does not release the memory after the rendering done or cancelled, Only releases if it crashes or starts a new task. Looked it up but couldn't find anything beside NVIDIA's support link that is in the error itself. Doesn`t prompt the error every time
We tested the same software setup with couple different hardware setup and this only occurs with virtual gpu setup
Systems that are working fine
Intel i9 9900 - Quadro 4000 - Standalone workstation - Uses 6.4GB VRAM for rendering the scene
Threadripper 2950x - RTX 3090 & RTX2080ti - Standalone workstation (3090 11.2 GB - 2080ti 8.4GB individually for rendering the scene)
System that having issue
Epyc 7H12 - 16 Procesor Assigned - A40-8Q - 8GB assigned - VM - (Exceeds what is needed for Quadro 4000 and Crashes after reaching 7.7GB VRAM for 15-20 Seconds)
For sanity check no issues with CPU rendering and assigning more than 8gb VRAM solves it but if it fits in a standalone RTX Quadro 8000 with 8gb it should managed it on vGPU. Also again for sanity check when I push the 12gb version to its limit it gives a proper not enough VRAM or OPTIX error as expected
Also tried with MtoA 4.2.4 - Still Same issue
The Same scene exported as .ASS to katana(4.0v5) and rendered with using 7.4-7.7GB VRAM but fails to release the memory and crashes after start rendering for second time.Also in Maya if I drop the resolution to save some VRAM it completes the render but doesn`t release the memory until it crashes or restarts a new frame
