🐛 Describe the bug
I am encountering a consistently reproducible deadlock/hang issue while using the vLLM multi-node API service.
When I send standard text generation requests to the /v1/completions endpoint, the dual-node GPUs return results normally and quickly, even if the prompt is very long.
However, the moment I include logprobs in the request parameters, the API request hangs indefinitely. During this time, GPU utilization remains stuck at 0%.
