Vray light crashing render nodes

[paco_higham]

I'm rendering a project out on my render nodes using 3dsMax 18.4 and V-ray 3.6.4.
My nodes are crashing every other frame and backburner is giving me this error report (see attached photo).
It's a very simple setup with just a single disc light, but it's weird that it'll render the first frame no problem but when they go to render the next frame it all crashes.
Any ideas?

Hi, does that happen with every scene or with a certain one only? Could you send us at support@chaosgroup.com the logs - vraylog.txt files from the render nodes (located in %TEMP% folder), after the problem appears? Please attach also the scene if the issue happens with a certain scene only.
I suppose you're using Backburner 2018 - is that correct?

Attached is the vraylog from one of the nodes.
I had hoped that another file would solve the problem, but regardless of what I'm trying to render, it does the same thing and gives the same error.
You are correct, I am using Backburner 2018.
