PID 1.5 stuck when dynamic vram is on

dynamic vram still is very unstable. PID 1.5 often stuck, i have to restart comfyui. vram must have overflowed to shared vram. when i turn it off using --disable-dynamic-vram --disable-pinned-memory and set a large reserved vram, everything is fine again. never stuck .

So，please do not remove --disable-dynamic-vram

No file, test, or entry point is named. First reproduce the PID 1.5 workflow with dynamic VRAM enabled, then compare it with --disable-dynamic-vram --disable-pinned-memory and a large reserved VRAM setting while collecting logs. Done means identifying a reproducible cause and preventing ComfyUI from becoming stuck when dynamic VRAM is enabled.
