Have you got any Railclone or Forest Pack in there?

3

If some of the render nodes are able to render the scene successfully, then check the memory consumption of the problematic nodes.
Do you have same amount of memory installed on all render machines ?

4

We do have both railclone and forestpro objects in many of our scenes. Ram is either 16 or 32GB on each machine.

5

Could be the same issue Bug: V-Ray DR Crash

We get it often with railclone & FPP, instanciating using the respective tools solves the problem, far from ideal though.

6

Possibly the same thing. What do you mean about instancing using the respective tools?

7

RC and FPP come with Railclone Tools & Forest Tools
They can turn the objects into regular instances and disable the RC/Forest object.

They are under the ‘hammer’ tab (no idea what this is called) → more → they will be both be in the list

8

Ok - I will pass that info on. Sounds like rather an annoying workaround. The weird thing is that I have only noticed this over the last week or so.

If you suffer this problem and use RailClone 2.2, please try with the latest RC 2.3 beta and tell us if there is some change.
We have included a fix in this release that would solve the problem, but we are not sure. This bug is not easy to reproduce, and until now we only got the crash using RC 2.2.

Thanks,
