Topic Description

Detailed Description

After installing Local Nucleus Service 2023.2.5 it starts Search Servicev.3.2.10-1033 as omni-search-service, which eventually will kill SSD because it runs ~5M/s disk IO non stop forever (followed this behavior for a week on a number of local servers 24/7).

I would recommend for all users to disable it from startup using config panel in http://localhost:3080/

Steps to Reproduce

  1. Install latest Isaac sim and Local Nucleus Service, all default paths and settings
  2. run sudo iotop

We have not seen this issue before. Can we please get your Nucleus and Search Service logs located in~/.nvidia-omniverse/logs/

Also, can we please get some more information about your configuration?
Is the data path for Nucleus on the same system drive as Nucleus is installed?
Had you seen any issues like this on previous installations of Nucleus on your system?
How large is the dataset that exists on your Nucleus server?
Do you have access to AWS s3 in your network?
