I also was ultimately able toreproduce on my machine.

What pwuzzles me is that a did a build that was successful. Then I
cleaned and did a rebuilt form scratch and it failed. And the failing
file is never the same, which leads me to think it depends a lot of the
order of files as returned by readdir()...

And in any way, the size is already approaching the limit, so it does
make sense to increase it.

OK, so what is weird is that we all noticed different failing files or
directories (busybox for Ricardo, shm for me, others for Leon), while
the Gitlab-CI runners all failed on nfs_check, whether on Ricardo's or
the main Buildroot jobs...

Anyway, as I said; let's increase the size.
