Are you able to reproduce the issue every time? (If yes, how?) :yes, shot down sketchup, and sometimes windows too
Error in Ruby Console? (Window > Ruby Console) : no

CPu render works well. but GPU(RT) render didnt work Continuously.

This sounds like a V-ray issue. This is beyond my control.
You should contact Chaos Group directly.
