Why does DAZ shuts down when Rendering

Avenel

When I Render what seems to be a low ploy scene, DAZ would abort the rendering with saying, DAZ Studio has become unstable, or it just vanishes completely with out any error messages. Why is that?

To help assess the problem, maybe provide some specs on your system.
One common issue that can cause this is insufficent ram, but if the scene has relatively few items maybe some other cause may be the problem.
There is also a log file you can access under help/trouble shooting, check and see if there are there any errors listed here after the render engine starts?

Almost guaranteed a ram issue. I have 16 GB and scenes with more than 4 Genesis figurs crash some renders

The shutdowns could be caused by a geometry the rendering engine (3Delight?) doesn't know how to interpret or it could be an issue with a texture, bump, displace, or reflection.
If the shutdowns occur just as the render is attempting to start it could very well be memory related, but if it's shutting down at a specific part of the render you may want to remove the item it's trying to render when the shutdown happens the next time you load the scene and attempt to re-render. In those cases you can sometimes isolate the problem by ditching that object or by exporting and reimporting the object as a static obj prop inside Studio (File>Export>..., FIle>Import...) but as Razor 42 stated it's hard to tell without your system specs.
System Type, System RAM, OS, GPU Model (shared RAM or Dedicated card?, and are the drivers Up-To-Date?)
