The IsaacSim4.2 is very unstable on a PC with 4 GPUs

Omniverse Isaac Sim

On a PC with 4 GPUs, the following operations cause crashes. It is very unstable.

Is there any solution for this issue ?

*NOW I am using the IsaacSim4.2 by a single GPU.
*Composer work well by 4 GPUs.

Environment:

HP Z8 G5
GPU RTX RTX6000 ADA x 4GPUs (Driver 553.09: latest)

  • I tried to use Driver 537.70 , the result was same.(IsaacSim4.2 was freese)
    Memory 128 G
    Windows11

Operations01:

1．Start IsaacSim4.2
2．RenderringMode is Renderer（Real-Time）
3．Change Rendering Parameter for Renderer（Real-Time）

Automatic Tilling : OFF
Tile Count : 1 ----> 4 ←—（Try to change from 1 to 4)
Tile Overlap : 128
GPU 0 Weight 0.0
Mult-Treading : ON

4.When I change “Tile Count” . Apllication was freeze
5.Crash Report (Already pressed the Subject Button)

Operation02:

1．Start IsaacSim4.2
2．RenderingMode is Renderer（Real-Time）
3．Just change RenderingMode from Renderer（Real-Time） to RTX – Interactive (Path Tracing).
4. Apllication was freeze

Additional Information:
I see SYSTEM LOG for Windows 11 , it is no GPU error.
