NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver

Hello, I have strange problem, all was good and worked well, but at one moment new vm dot start. When I try to check problem, after “nvidia-smi” command I have “NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver…”. I try reinstall driver once and problem was solved, but at next day I have this problem again and reinstall driver dont help, what can it be ?

Always worth a search in the Knowledge Base - http://nvidia.custhelp.com/app/home/
