Cuda Error 185

[retrorecall]

Hi, I recently have one file that I keep getting this error.
It's a simple geometry block with materials assigned to the items in the block. Rendered in an HDRI scene.
It pops up occasionally after I open a render view port (see attached)
It hasn't occurred in any other file so I'm guessing maybe there's a setting issue?

i'm on Version 6 SR27 of Rhino
(6.27.20176.5001, 6/24/2020)
Octane 2020.1.0.121 Studio

Any help is appreciated,
thanks!

I suggest updating to the latest version of the plugin, and if that does not resolve the issue, please let me know.
