HTOA 3.x.x instance render bug ?!

In previous version 2.2.3 when i use INSTANCE and point attribute "instance" with for example "/obj/geo1" and render - all ok! Htoa use "/obj/geo1" as instance and correct render, low memory, etc. In version 3.0.0(3.0.1) when i try render same scene or use same method - htoa quickly takes all my RAM... Finish 😞

In new version something changed with instance or this is bug?

Thank you...

I just rendered a simple test with 100k instances with the Instance object. Do you have repro scene (as scene that reproduces the problem)?

First screenshot is 2.2.3 version - all render OK(!), Second - 3.0.0 - all memory occupied in few seconds, computer freeze and full finish 😞

I tested on two different computers with Linux and Windows ...

The question remains open ...

And yet it was fine for me with HtoA 3.0.1

Can you post an Arnold log?
