--- Comment #10 from Jimmy Olgeni <olgeni@FreeBSD.org> ---
Just a quick note that I'm seeing this regularly on some VMs, and physical
hosts to a lesser degree.

For some reason running "pkg upgrade" on py39-ansible seems to be a sure way to
trigger this on the affected boxes.

===

The following 1 package(s) will be affected (of 0 checked):

Installed packages to be UPGRADED:
        py39-ansible: 7.1.0 -> 7.6.0

Number of packages to be upgraded: 1

The process will require 10 MiB more space.
[1/1] Upgrading py39-ansible from 7.1.0 to 7.6.0...
[1/1] Extracting py39-ansible-7.6.0:  38%
pkg: Fail to chmod
/usr/local/lib/python3.9/site-packages/ansible_collections/community/general/plugins/modules/__pycache__/.pkgtemp.django_manage.cpython-39.pyc.ub2f8mxmwp9S:Bad
file descriptor
[1/1] Extracting py39-ansible-7.6.0: 100%

===

The affected path is never the same.

I ran "script LOG truss -f pkg upgrade -y py39-ansible" in the hope of getting
useful data - it was very slow but it worked on the first try, so there may be
some timing issue involved? :|
