Hi, Maxim Cournoyer skribis: > I've tried with the following modified version which runs multiple > threads in parallel (to mimic --max-jobs=4 on the daemon), and I've yet > to trigger it, although the hard drive is grinding heavily: Note that ‘--max-jobs=4’ leads guix-daemon to spawn 4 ‘guix substitute’ processes, which is not what the script is doing here. Are the other conditions the same, for instance same network, etc.? Thanks, Ludo’.
