When does this happen?

IF Deploying vLLM in Docker (or any environment) results in zmq.error.ZMQError: Operation not supported during engine startup.

How others solved it

THEN Try adding the `--disable-frontend-multiprocessing` flag to your vLLM serve command to bypass the multiprocessing ZMQ layer. If the error disappears, the root cause is likely insufficient GPU memory; increase the allocated GPU memory or reduce model memory usage (e.g., lower max-model-len, max-num-seqs).

vllm serve <model_path> --disable-frontend-multiprocessing --max-model-len 10240 --max-num-seqs 2
