🐛 Describe the bug

I'm doing this via python -m vllm.entrypoints.openai.api_server --port 7801 --host 0.0.0.0 --model /mnt/model/llama3-70B-instruct --served-model-name vllm_llama3_70B_instruct --tensor-parallel- size 4 --trust-remote-code After deploying llama3, we started to perform performance tests on the model concurrently. The model could reply normally at the beginning, but about 10 minutes into the test, vllm reported the following error (I installed vllm through the source code 0.4.1):

Would you kindly share the specifications of the GPU you utilized while encountering these issues? Also A800-80G?

[ywang96]

@ericzhou571 @JPonsa @blackblue9 @supdizh Could you try --disable-custom-all-reduce when you launch the server and see if this issue persists?

[JPonsa]

@ywang96 the issue persists when launching the server with --disable-custom-all-reduce

[Warrior0x1]

I encountered a similar issue in version 0.4.2.
