System Information
Operating system: macOS-13.5.1-arm64-arm-64bit 64 Bits
Graphics card: Metal API Apple M2 Pro 1.2

Blender Version
Broken: version: 3.6.2, branch: blender-v3.6-release, commit date: 2023-08-16 16:43, hash: e53e55951e7a

Short description of error
I get some of these intermittently: Context leak detected, msgtracer returned -1
render ultimately fails (always at around frame 400) with this:

CommandBuffer Failed: cycles_metal_integrator_reset

Refer to the Cycles GPU rendering documentation for possible solutions:
https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html

CommandBuffer Failed: cycles_metal_integrator_init_from_camera

Exact steps for others to reproduce the error

download and extract the files attached to this issue
run render.sh + wait until blender crashes

~~using the opengl backend, it works just fine~~

Thanks for the report, @horatio_engelmann.

This description is a bit confusing. OpenGL Backend is used only for drawing the interface and for the engines Workbench and Eevee. It's not much related to Cycles.

Could it be that you meaning to compare CPU vs GPU(Metal) rendering?

Note also this bug report could potentially be a duplicate of:
#106900: Blender 3.5 and 3.5.1 are crashing while using Metal as backend.

ok, weird. during my tests I was using --gpu-backend opengl once, in which case it rendered all the way through.
that was just a coincidence then, I suppose.
just ran it again, and this time I was getting the same error.
