Not responding after render ends

[fAEkE]

I'm rendering an underwater scene to which I've modelled a fallen tree. Without the tree I have no problem, but with it in the scene Vray will freeze when the render is finished or when I click cancel. The tree is pretty high poly but not That high. I have displacement on (3d displacement, vraydismodifier). Anyone have a clue what the issue is?

The scene uses about 6gb of 16gb memory when rendering atm. So no memory issues..

Got better when I changed to 2D displacement. Can someone explain why Vray would freeze after rendering with 3D displacement?

Please send the scene to support@chaosgroup.com or peter.matanov@chaosgroup.com for investigation.

Thanks, I have emailed the scene.
