Arnold is constantly crashing

Hello there.

I keep getting a crash when I try to bake textures in Arnold using MtoA. Below is the error that i'm always getting. I did a cleanup geometry operation, but the crashes still happen.

Any ideas?

* CRASHED at 00:00:00, pixel (147, 256)

I realize this is an old ticket, but if anyone else comes across this, https://forums.tomshardware.com/faq/how-to-fix-windows-10-error-%E2%80%98external-exception-e06d7363%E2%80%99.2752246/ has some interesting insights for what might be going on and how to maybe fix it on your machine

Nope, Just when doing a texture bake from Maya.

Cheers

It's hard to reproduce. It does not happen with the same shape repeatedly. Sometimes it does, sometimes it doesn't.

We are also seeing that when we bake textures on a lot of geometry objects, Maya's memory consumption sometimes goes way up.

It seems like there is a memory leak somewhere. I will try to follow up with more info as I find it.

Sincerely

Is this happening with other apps besides Maya?

That's pretty generic. Got a repro for it?
