LuxCore testing hdri's.
This scene has been crashing often.
No mater what HDRI I use it crashes most of the time.

I need a test scene to investigate the problem.

Here is the same test scene without the HDRI.
Would of been to big to send with it.
Take a break. Doesnt any body here, take breaks.

It is working fine here. How big is the HDR you are using ? It may be simple the same problem of the other thread: out of memory => crash (however it would crash always, not only some time).

Other programs consume VRAM, too. Maybe it barely fits into the graphics card and if some other program reserves a bit more VRAM, it begins to crash.
However it's hard to speculate if we don't know exactly how this was tested.

The size of Hdri is 25.3 MB.
There are 2 graphic cards and each one has 8GB Vram.
I do not any other window running except blender: LuxCore when rendering.
I do not know what software to use for Vram monitoring so
I just opened the Task Manager to see memory:

With the same scene, I have used Cycles renderer without any crashes.
When LuxCore is rendering, it works very fast and rendered that same scene in only 27 Seconds.

Try to post the complete scene somewhere like dropbox, google drive, etc.

Ok, I found a cloud to store it on:

You did not pack the HDRI file.

I don't really see how this scene can lead to a crash, it's a bunch of boxes (very low polycount), only thing needing VRAM is the HDRI.
It also uses Path+Sobol with reasonable depth settings.

I suspect the graphics card driver you are using maybe has some problems.
Can you post which graphics card model exactly you have?
Also check if there are newer drivers available (but I guess you've already done that).
