[Usage]: 使用vllm的docker镜像启动Qwen/Qwen3-32B模型服务，CPU占用一直100%

[zailushang2006]

Your current environment

vllm：0.8.5

How would you like to use vllm

使用vllm的docker镜像启动大模型服务，vllm版本为0.8.5。 部署的模型师为Qwen/Qwen3-32B。 当指定--tensor-parallel-size=2时，在日志中可以看到有两个VllmWorker和相应pid。这两个进程一直占用100%的CPU。我的服务器是64核CPU，其中这两个进程的CPU一直是100%。 这个问题如何排查和解决？

遇到相同问题，不过镜像版本是0.8.5.post1，8卡4090启动模型后，闲时CPU也一直100%。不确定是否要升级或降级vllm版本？
