[Fatal] [gpu.foundation.plugin] Out of resource descriptors

If you get the error message [Fatal] [gpu.foundation.plugin] Out of resource descriptors when running Pegasus Simulator, it likely that you are getting above the default limit on the number of file descriptors allowed per process Ubuntu 22.04’s, which is 1024 by default. When using multiple GPUs, Pegasus Simulator on Isaac Sim 4.5.0 uses closer to 1382, leading to Isaac’s Vulkan API back end to crash. Raising that system wide limit may solve this issue. You can do this by following these steps:

1. Open a terminal and run the command:

   sudo nano /etc/systemd/user.conf
   
   find, uncomment, and set DefaultLimitNOFILE=65535
   

2. Again, modify the following system file:

   add the following two lines just above the "# End of file" at the bottom of the file:
   
   * hard nofile 65535
   * soft nofile 65535
   

After this you will need to reboot your machine, but after that, Pegasus Simulator should be working fine on Isaac Sim 4.5.0.
