Why doesn't the VLLM-related process disappear after the program reports an error, the vllm process will always occupy the video memory, but the request interface will always report the same error
Why doesn't the VLLM-related process disappear after the program reports an error, the vllm process will always occupy the video memory, but the request interface will always report the same error
You need to manually kill the VLLM-related process and then restart the asynchronous service to restore the normal process
