ISAAC Sim just crashes abruptly

Omniverse Isaac Sim
1

While working on ISAAC Sim, it just crashes at random moments. No warnings or any sort of logs. I am having issues while working because I don’t even get the chance of saving my work.

I am launching the app from Omniverse in normal mode and ISAAC Sim version is 2021.2.1

Anyone facing the same error please comment below. Let me know if there is any method by which I can launch ISAAC Sim from terminal and redirect all the logs to a file.

System specs:
GPU - NVIDIA RTX 3090 (24GB)
CPU - AMD Threadripper (16 cores)
System RAM - 128 GB

This is still true for version 2022.1.1, it crashes a couple times every day, or hangs and requires a hard kill.

The location of the log files is at ~/.nvidia-omniverse/logs/Kit/Isaac-Sim.
Please provide a copy of your log file and the steps to reproduce the crash.

@omers , are you still seeing the issue?, if so, please share the log file as requested in previous message.

We also run Isaac Sim 2021.2.1. We don’t experience crashing even when running all day. This is with Core i7 and different PCs with different RTX cards.

However, we have to disable sleep or make sure to exit out of Omniverse completely before letting the computer go to sleep. If the PC goes to sleep while Omniverse and Isaac Sim is loaded, even if in stopped state, then after the PC wakes up, Omniverse doesn’t work right.

Hi. Does this issue still happens with Isaac Sim 2022.2.0? Please share the log file when the crash happens.

I am also getting random crashes, here are a few just from today, I will add more with time, as it crashes all the time… Seems like there is no QA running on it, at least not with Ubuntu.

@omers when does it crash? Immediately after loading Isaac Sim or when opening a scene?

You GPU meets the minimum requirements of 8GB VRAM. This could cause a crash when opening very large scenes. Try watching your GPU VRAM usage.

Other things to try:

  • Connect your laptop to an external monitor.
  • Update to the 525.x drivers.

@Sheikh_Dawood Some of the logs are crashes immediately when opening, some after running simulation with OmniGraph nodes. Scene is very small, only a single robot.

I am already connected to external monitors.

I will try to update the drivers.

Try take a look at nvidia-smi before loading Isaac Sim if the GPU resources have been completely cleaned up.

There could still be some GPU memory leaks.

Maybe increasing your SWAP size may help too.

Start a scene with one camera then add more cameras while watching the VRAM usage. Usually, simulating cameras/viewports will use a chunk of VRAM.
