Memleak in NVENC/NVDEC on 378.13 drivers

Hi, we are facing memleak on latest stable drivers 378.13.

We are using 4x Quadro P5000 cards and encoding around 100 HD channels on one system with ffmpeg, fully on HW with adaptive deinterlace NVDEC and NVENC to h264 with B-frames.

After upgrading from 375.26 -> 378.13 our system memory 128 GB will be full after 24 hours of encoding, i can see growing memory usage, downgrading back to older drivers fixed that issue.

Anyone else facing same issue?
