Trying to run native ATLAS again on WSL2 Ubuntu but tasks are failing and I'm not sure why. Here's a link to the log of the latest task: https://lhcathome.cern.ch/lhcathome/result.php?resultid=432064796 Any ideas would be helpful.

I don't have the expertise to understand all the logs, but this caught my attention:

02:48:23 (333): wrapper: running run_atlas (--nthreads 1)
[2026-01-29 02:48:23] Arguments: --nthreads 1

Don't ATLAS tasks require more than one thread to run?

I don't think so. I used to run them single threaded, could never get them to run multi-threaded under WSL2. Now they fail even single threaded and I don't know why. It's been a while since I ran them so the app may have gone through some revisions.
