I’ve seen it too, and I think it might be the same issue as described
here:

  https://git.savannah.gnu.org/cgit/guix/maintenance.git/commit/?id=cdef930632d0a94b0d92bf4f5fc7227e75c6eb10

If that happens again, could you log in the target machine as root and
run:

  find ~/.cache/guile | xargs ls -lrtd

That way you’ll see if some .go files have just been compiled, and also
if there are temporary .go.XYZ files in there (stemming from an
interrupted compilation process due to the timeout.)

Thanks,
Ludo’.
