Isaac sim RAM issues

[jonatan.bergstrom]

Hello,
Isaac sim seems to eat up a lot of RAM when switching between USD files. switching through a few vehicle models(game models exported from Unreal) that we have on our nucleus server. Isaac sim quickly allocates all of my RAM and the either crashes Isaac sim or causing the OS to crash. I have increased my swp memory size to mitigate this issue but it issue persists. Is there something I have forgotten to configure or is there an issue in the sw?

My setup:
Isaac sim V: 2021.1.1 (from the launcher)
Mem: 32GB
HDD: 240 GB
CPU: AMD® Ryzen 7 3700x 8-core processor × 16
GPU: NVIDIA GeForce RTX 3090/
OS: Ubuntu 18.04.5

Hi,
I read somewhere from someone at Nvidia that excessive RAM consumption was a known issue they are trying to fix.
I also work with 32GB of RAM, and I increased my swap to 16GB. Not an ideal solution, but it solved the frequent crashes for me and it is way cheaper than buying a new set of RAMs.

I hope it helps.
