Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1650 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.93.0, branch: master, commit date: 2021-06-02 11:21, hash: 84da05a8b8
Worked: (newest version of Blender that worked as expected)

Short description of error
Blender crashing after shifting from preview to rendered after some time when blender starting completing image on viewport, this same when trying generate render image.
In b2.92 the shifting giving sometimes info about "Out of memory" for blenderman.blend file, but in status bar not seing something that my device is to slow or weak for this alert.
The blenderman.blend have transparent background and this can be problem maybe. In other project time ago I meet this same, and when I limited light as black background layout with dark garage to present some car - project wasn't to much advanced and problematic in my opinion, but this was problem for GPU and CPU too.. it was impossible to generate full image with setups of point lights from car reflectors. I get some advanced splash demo to do test, and here are logs uploaded to check.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]

I downloaded file as blenderman.blend waited for compilation in solid mode
I shiften from solid to shadow or tried render image

Can you check if you have enough resources during rendering (RAM, VRAM)?

I wasn't able to reproduce any crash.

Could you please upload C:\Users\User\AppData\Local\Temp\Blenderman_1.crash.txt?

Could you also try the latest 3.0 version? The debug text has errors where Calloc and Malloc are returning null. This area of the code for Windows was just updated recently, and it might solve the issue you are experiencing.

Blenderman_1.crash.txt is not produced. How to generate this?

edit: I see.. in Temp.. but it's empty file alwayas.

I'll try do tests with latest 3.0.

Just checked system info, I see quite a few of addons enabled, so I would like to check if there isn't any problem.
Please click on File > Defaults > Load Factory Settings, then load .blend file and render. Does this resolve the issue?

On b < 3.0 not resolving, b 3.0 working with some of this and without this same.
My opinion is that must exist some memory leak not supported to prevent crashing.

Allocating 14-15GB for this project sounds normal?

It uses about 14GB with GPU rendering (openCL). When you take into account memory fragmentation, this can easily cause out of memory situation.

While we want to improve Blender to handle such cases memory gracefully, this is not currently considered a bug.

Doesn't this problem correlate with this VRAM computation problem?

From what I know, Blender gets VRAM info from driver, so it this is incorrect, you can only blame driver.
Issue here is with RAM though, and there are thousands of places where code doesn't expect that you are out of memory, so program will crash. It's a lot of work to make sure, that program won't crash and it's not priority currently. Ultimately it can be terminated by OS if it happens that it needs some resources for itself, so you have to take HW constraints into consideration when doing resource intensive operations.

Thx for answer. I observing similar problem around crashing when simulating cloth and baking animations. Soo.. hard work on CPU/GPU and RAM hanging blender or crashing and exist problem to pause current process or thread of computations.

Other version crashing 3.0.0 Alpha, branch: cycles-x in case 3.0.0 Alpha not.

I trying compare cycles-x, k/e-cyckles

Want report that, if viewport i set for Solid then often not crashing when going to render, but when viewport is Shading then when rendering image crashing. Need some improvements here around memory management I think.

Looks it's important that render is made in new window or in this same (eg.e-cycles version changed 3DViewport workspace into Image editor where we see render process.
