Hi all,

I'm able to run native ATLAS on WSL2 Ubuntu 20.04 as single core only. When I change preferences to use 2 cores the tasks fail as "Validate Error" after about 15 min. of runtime. I was under the impression that once you get ATLAS running and with enough RAM you should be able to run any core configuration. I was able to run native multicore ATLAS on Hyper-V prior to learning of and switching to WSL2. Haven't been able to get Theory to run on WSL2 either but that's a separate question for a different thread. Is this a limitation of WSL2? Any ideas to try? Thank you.

Here's an example of a failed task:
