agent: infrastructure

When does this happen?

IF ZMQError: Operation not supported occurs when running vllm serve in Docker or when GPU memory is insufficient for the engine to start.

How others solved it

THEN Add --disable-frontend-multiprocessing flag to the vllm serve command to bypass the multiprocessing socket issue, or increase GPU memory allocation to ensure the engine starts successfully.

vllm serve /path/to/model --disable-frontend-multiprocessing
