Arnold memory leak - running standalone Arnold as a solution?

[designimation]

As others have reported, I'm encountering a memory leak and render times increasing greatly during the course of a GPU render sequence.  This is with Maya 2023.1.  I haven't found any consensus on a solution.

I found a reddit thread from 2018 where a user describes definitively fixing the issue by using the standalone Arnold.

Just wondering if anyone can comment on that.  I've seen other contradictory reports that Arnold only works via MtoA.

As reported in the forum, this is a known bug and the (relatively) easy solution is to revert to using Maya 2022.1.

It's been years - sure wish Autodesk would finally get the GPU renderer to have parity with the CPU in terms of features and reliability.

Is this an issue still in the 2023.3 update just released?

2023.3 doesn't have the most recent Arnold. We had to hand off a version of MtoA to the Maya team, and since then we released MtoA 5.2.2 and MtoA 5.2.21

I don't think we've ever reproduced this memory leak. For the first couple of frames, yes, but not enough to use up all available memory.

Hi Stephen.

Do you want me to send you my archived scene file with the GPU leak?

I would like to see it if you don't mind.
