Isaac-sim 4.0 crash and shows an error "[Fatal] [gpu.foundation.plugin] Out of resource descriptors!"

Hello Omniverse team

I need to construct 20 UI widgets within the scene. Attached is my code. You can run this standalone application script in the Isaac-sim 4.0 environment to reproduce the issue. This code works normally in Isaac-sim 2023.1.1, but in Isaac-sim 4.0, it causes the simulation to hang or crash after running for more than 10 minutes. The error log shows “[Fatal] [gpu.foundation.plugin] Out of resource descriptors!”. Please help me resolve this issue.

error log:
2024-06-25 02:46:21 [360,187ms] [Fatal] [gpu.foundation.plugin] Out of resource descriptors!
2024-06-25 02:46:21 [360,187ms] [Warning] [gpu.foundation.plugin] Sync scopes:

Fatal Python error: Segmentation fault

Steps to execute my standalone application script:

  1. unzip main.zip and copy main.py to Isaac-sim 4.0 installation folder ~/.local/share/ov/pkg/isaac-sim-4.0.0
  2. open the Terminal
  3. cd ~/.local/share/ov/pkg/isaac-sim-4.0.0
  4. ./python.py main.py
  5. wait 10 minutes

Hello,
The issue still exists in Isaac-sim 4.2.
I submitted another issue here.

Can you try setting these settings, either in a kit file:

[settings.rtx]
descriptorSets=60000
reservedDescriptors=500000

or as commandline arguments

--/rtx/descriptorSets=60000 --/rtx/reservedDescriptors=500000

Thank you for the hint, we’ve got the same problem and unfortunately the problem persists.
We are working with KIT 106.3 SDK and have a lot of overlay widgets (implemented as omni.ui.scene.Manipulator), which are updated regularly - for us that is causing the crash mentioned

I also encountered this issue even if the arguments are applied.

is there any alternatives to create UI widgets?

It seems that Isaac Sim 4.5 has fixed this issue.
