17b8: I am experiencing multiple crashes during the render. No error messages, just PC is rebooting.
It happens at the different clips in the queue; the problematic clips are rendering successfully after rendering job update and restart.

Windows 10, NVIDIA 1070 with the latest Studio driver; nothing crazy in nodes - just the very basic corrections and stabilization; deliver as individual clips; CineDNG sources, AVI Uncompressed 10Bit YUV 422 delivery. The log is attached.

Here is my rendering issues:
H265 - Using NVIDIA render engine - Crashes
H265 - Using Intel Quick Sync render engine - Works
H264 - NVIDIA without Frame Reordering - Works
H264 - NVIDIA with Frame Reordering - Crashes
H264 - Local works.

H265 - NVIDIA with (Full Frame) still images turned off works.
(the problem with still images was here before in version 15 and was resolved)

I would render H265 with still images turned off and the render will work; I would then turn on
the still images and run the render again and it would work. If I start off with the render that
includes the still images, it would fail. This may tie into the caching, memory allocation issues
seen in the log.

Windows 10; NVIDIA 1080; went back to the latest patch 461.40 Ram: 64GB

Extract from my System Log:
There are some problems allocating memory which is a part of the problems.
