Faced with a problem "HandleAllocator arena is full, using slower system heap"

[xarlammm]

Everything worked great until I loaded a relatively heavy model. The
"E/Filament: in allocateHandleSlow:82
reason: HandleAllocator arena is full, using slower system heap. Please increase the appropriate constant (e.g. FILAMENT_OPENGL_HANDLE_ARENA_SIZE_IN_MB).
E/Filament:
A/libc: Fatal signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 0x7776435000 in tid 13032 (ugmentedreality), pid 13032 (ugmentedreality)"
error occurs with the loadGlb() function. What to do in such a situation? I'm adding the package to build.gradle. Using 3D Viewer on android.

Can you provide more detail about the crash?

• the full log (as an attachment please)
• information about your device

Could you send us the model that causes the crash?

Ah, the problem is actually this message:

E/Filament: Panic
    in flush:88
    reason: Backend CommandStream overflow. Commands are corrupted and unrecoverable.
    Please increase FILAMENT_MIN_COMMAND_BUFFERS_SIZE_IN_MB (currently 1 MiB).
    Space used at this time: 4761104 bytes

The model is just too big. We have a pending change that will allow you to configure this buffer at runtime -- however, I would strongly recommend to fix your model. These are mobile devices with limited resources, you shouldn't use models with so many draw calls. You need to use a library that optimizes your model geometry.

I did a test incrementing FILAMENT_MIN_COMMAND_BUFFERS_SIZE_IN_MB from 1 to 3, and FILAMENT_RENDER_PASS_SIZE_IN_MB from 3 to 4 as well as FILAMENT_PER_FRAME_COMMANDS_SIZE_IN_MB from 2 to 3, and the model was displayed. It has over 600 draw calls.

Thank you for the answer, which library can you recommend for optimizing the glb model?
It is desirable that it was under Android
