In my case, it starts to download substitutes (but I have remove
--quiet), something like:

--8<---------------cut here---------------end--------------->8---
And I even tried with "-n21" and it seems ok.
I am running Guix on the top of Debian with ext4.

Well, I am not sure to understand, but in nix/libstore/build.cc,
"void UserLock::acquire()", there is:
--8<---------------cut here---------------start------------->8---
foreach (Strings::iterator, i, users) {
[…]
if (lockFile(fd, ltWrite, false)) {
[…]
return;
}
}
throw Error(format("all build users are currently in use; "
"consider creating additional users and adding them to the `%1%' group")
% settings.buildUsersGroup);
--8<---------------cut here---------------end--------------->8---
So maybe the file is locked for whatever other reason on your machine?
All the best,
simon
