Short description of error
[During visualization with Cycles, the program closes.]

Exact steps for others to reproduce the error
[I press F12, it takes some time for rendering, half the scene is visualized, and an instant departure from the program! Without any errors.]
[on simple scenes, such as "Cube" and 1 lamp did not detect crashes. Majak.blend -very bad render.

] Thanks for help!

Hi Pawal,
I couldn't reproduce your crashes, but suspect that memory limitations may be an issue with at least Majak.blend. During rendering here, memory requirements peaked at 10.4 gigabytes (this reported by my system monitor). If similar demands occur on your machine, with 16 GB, that leaves less than 5 GB for everything else - operating system and essential applications. I suspect Windows may be detect too much memory contention and is killing Blender. If Windows is stopping Blender, it will log the event. Check your system logs for any such messages. You could also try running Blender from a command line prompt (User Manual Details), where failure messages may be posted by Blender itself. If you have a colleague with a machine that has more memory or processors, try the files on that platform. The aim is to discover if you are just having lack-of-resource issues, or if something more like a rendering bug is an issue. With the material uploaded so far, I cannot make that determination. Sunduk.blend is less demanding of resources. If you are experiencing crashes with this file as well, it may be the better candidate for fault isolation for other-than-resource problems.

I rendered about four or five trials per blend file without issues - but this machine has more cores (40) and more memory (64 GB) so if lack of resource is the root cause, I'm probably not the first to notice. If resource contention is an issue, it is not a bug that Blender developers can fix. Some ambitious files require significant resources to render.

Here are two representative renders of Majak and Sunduk - I don't see anything particularly bad with either one. Post the results of any investigations you do here. Thanks!
