The log file (compressed) is attached.

In doing this I noticed that I have two guix-daemon processes running:

root      1583  0.0  0.0  33156  2412 ?        Ss   08:55   0:00 /root/.config/guix/current/bin/guix-daemon --build-users-group=guixbuild
root     13003  0.0  0.0  36028  6256 ?        Ss   11:28   0:00 /root/.config/guix/current/bin/guix-daemon 12770

I ran strace on the first one.
