sometimes the miner crashes with the error

cudaError 719 (unspecified launch failure) calling 'cudaMemcpyAsync(worker->device_hasher, worker->hasher, sizeof(blake3_hasher), cudaMemcpyHostToDevice, worker->stream)' (src/mining.h line 13)
Miner crashed with exit code 1. Respawning..

running GNU/Linux Ubuntu 20.04.3 LTS (focal) with nvidia-driver-460 (460.91.03-0ubuntu0.20.04.1) and nvidia-cuda-toolkit (10.1.243-3)

I suspect the nvidia driver. - anyone?
