When does this happen?

IF Pre-built vLLM CPU Docker image exits with 'Illegal instruction (core dumped)' and no informative error message on platforms lacking AVX512 support.

How others solved it

THEN Ensure the host CPU supports AVX512 instructions when using the official vLLM CPU Docker image. If AVX512 is unavailable, either build a custom vLLM image from source targeting the specific CPU architecture or use a CPU image compiled without AVX512. Verify CPU capabilities with 'lscpu | grep avx512' before deployment.
