Randowm crashes ... a little workaround

[Micha]

Since months I have the problem of random crashes during rendering. Today I need to render a lot of images from one Rhino file. I got crashes every few renderings (if I use DR), but found, if the frame buffer is minimized, I get no crashes. Maybe a trace for hunting the bug, but also good as workaround.

Looks like a display issue, seen under the usage of different graphic cards.

I also have that problem,I find that it will happen when I have a big space where there is nothing to render,or something that will render fast.

What is the exact version/service pack of V-Ray/Rhino and OS?
How much memory is occupied during the rendering and how much is available on the participating machines and workstation?

Does the crash occur if you render to VRImage with VFB mode set to Preview or no No memory?
How many GPU devices do you have installed on the machine and what is the drivers version?
Does it crash only when DR is enabled?

Rhino 5 SR 10
Windows 7/64 SP 1
Vray 2.25251

Not always the same ,even on very small drawings it will happen
I did not try to render to VRImage
I have one GPU device,nvidia quadro 4000 driver 9.18.13.4066

No it also crash when not enabling DR

It looks like the rendering is to fast and that the display can't keep up.

Can you send us one of those scenes which crashes along instructions how we could reproduce the issue into our environment?
Also would it be possible to render to VRImage files with VFB set to Preview/No Memory?

As soon as it happens again ,I will.
And I will try to render to VRImage

Thanks
