Arnold is crashing randomly while rendering image sequence

[Arthur_Vatine]

Hi there,

I'm working on Maya 2019.2 student version and Arnold is crashing randomly during image sequence rendering...

I can't get any log file, just some information from the Windows output :

Any idea ? I'm kind of desperate right now...

Is it crashing on every frame?

Why can't you get a log file?

Try to isolate what could be causing the crash. What is in the scene? Delete 50% and render until you find what is causing it.
