Description
**Describe the bug**
On my CentOS 7 operating system, when I tried to render a scene in Maya with a large amount of USD skeletons and skinned models by using "Interactive" render type, Maya would crash.
For your information, I tried the same test on windows 10 machine with similar settings, and Maya would not crash. Also, If I use "Export Ass and Kick" render type to batch render, Maya would not crash.
I've attached a sample scene file along with the crash info generated by Maya. I hope it would be helpful.
**To Reproduce**
Steps to reproduce the behavior:
1. Start Maya
2. Open the scene attached
3. Use Arnold Renderer to render the scene using "Interactive" render type
**Expected behavior**
The scene should be rendered without crashing Maya.
**Used Software Versions**
- mtoa: 5.3.3.3
- maya-usd: 0.24
- Maya: 2023.2
- OS: CentOS7

Research direction
Start with the attached test_skel.zip scene in Maya 2023.2 on CentOS 7, using mtoa 5.3.3.3 and maya-usd 0.24. Compare Interactive rendering with Export Ass and Kick, and review the attached Maya crash information. Done means the sample scene renders interactively without crashing; the payload names no source files or tests.
