🐛 Describe the bug

I'm using Llama3.1 to do inference, and container is crashed.

My command to start vllm:

        image: vllm/vllm-openai:v0.5.3.post1                                                                                             
        command: ["python3", "-m", "vllm.entrypoints.openai.api_server"]
        args: ["--model", "hugging-quants/Meta-Llama-3.1-70B-Instruct-AWQ-INT4", "--host", "0.0.0.0", "--port", "8080", "--tensor-parallel-size", "2", "--trust-remote-code"]

Logs when container is crashed:

Hi @tonyaw this is a known issue that should be resolved by #6798. We will publish a new release this week with this included.

[tonyaw]

Thanks for your info. Is there any WA to avoid the crash?

[Minami-su]

The same issue still occurs when using Qwen2 72B Instruct with vllm 0.5.4.

[mgoin]

@tonyaw please try upgrading to 0.5.4

@Minami-su can you share your command, system details, and stacktrace?

[Minami-su]

@tonyaw please try upgrading to 0.5.4

@Minami-su can you share your command, system details, and stacktrace?

[tonyaw]

It looks like the backtrace is same as #7297
But the container is hang instead of crash.

[tonyaw]

Please see my previous message.
It looks like this issue isn't 100% fixed.
Could you please help to confirm?

[liho00]

same issue with 0.7.2 vllm
