Single frame, or animation? What are the temps like? Just this scene, or all scenes? Can you share the scene via private uploader? Have you stress tested the system via some stress test software? Are you running out of RAM (doesn't look like it, no warning though?)

Hi TomG
-Single frame, or animation?
Single frame.
-What are the temps like?
Cpu 66C- water cooling.
-Just this scene, or all scenes?
This is my first scene in corona.
-Can you share the scene via private uploader?
Its need a permission from my boss... i will see.
Have you stress tested the system via some stress test software?
i usualy use other 3d software. and now i test with (HeavyLoad) software and every thing is ok.
-Are you running out of RAM (doesn't look like it, no warning though?)
I think no.

Is it the same if you create a new scene with a single teapot and 1 light source? (and use Corona)

No. for now it's only this scene... I have worked another several small scenes and it's ok , no problem

Are you using any scripts/plugins in the reported scene?

[maru]

Maybe you can remove most stuff from that scene, and only leave the part which is causing the issue, and then send it to us?
That process could also help diagnose the issue. :)
