Omniverse Isaac Sim

Hello, Isaac Sim crashes once listen to a topic from a different terminal.
I create an empty scene with an omnigraph that just publishes the clock like so:

Then i just try to listen to this topic using ros2 topic echo clock
and isaac sim stops responding and crashes after a few seconds (memory gets to 100GB/270GB)

Sure thing, here is the newest log. My PC is handling it well today 😅. It is not crashing but once I listen to the topic, memory gets to 80-100GB (same thing happening on my laptop), and the scene becomes very slow, and stopping the scene takes around 1-2 minutes. When the scene stops the memory consumption gets back to normal.

I tried uninstalling and reinstalling isaac sim on both my laptop and my pc, the issue is resolved on my laptop, but it still persists on my pc.
