Dear @lizhensheng, The error code indicates, resource is busy([https://developer.nvidia.com/docs/drive/drive-os/6.0.8.1/public/drive-os-linux-sdk/api\_reference/group\_\_NvSciError.html#ggaef993f18ba16be8c8554d9d8538c5938a8a4d3f489b06138bad71519371a52b4d](https://developer.nvidia.com/docs/drive/drive-os/6.0.8.1/public/drive-os-linux-sdk/api_reference/group__NvSciError.html#ggaef993f18ba16be8c8554d9d8538c5938a8a4d3f489b06138bad71519371a52b4d)) . I believe it also happens when the previous run has no graceful exit and both the issues are related. Could you share the `ps -aux` log when you hit the issue. ---
