Gray renders using Arnold

[Anonymous]

Hello,

I am getting Gray renders when i use arnold. Not all the time but often.
Some times re-starting houdini helps but not often.
I have original Houdini Version 17.0.416

Which version of HtoA? Do you have any renders/scenes that show the effect?

What is in the scene? Which shaders are you using? More information would be useful.
