Not sure if it will help since it looks like the issue is more low-level, but feel free to try out some very new functionality for debugging threading issues using Dawa -- https://git.sr.ht/~bduggan/raku-dawa#multiple-threads https://raku.land/cpan:BDUGGAN/Dawa Perhaps stopping the threads and then stepping through statements in each one can help to hone in on the race.
