I'm glad the problem went away. :-)
Updates and upgrades have broken my systems more times than I care to
remember. Now, I take an image of the system drive before upgrading a
machine. If an upgrade misbehaves, hopefully I will catch it quickly
and can simply go back to the previous image. Otherwise, I need to
include backup/ restore of system configuration files and/or data when
re-imaging.
Perhaps you should consider setting up a staging/ testing environment,
update/ upgrade that, and run tests. If everything looks good, then
upgrade the production environment.
The length of your 'pkg upgrade' output suggests that you might want to
upgrade more frequently. This should give you a smaller haystack to
search if and when an upgrade causes problems.
All of the above might be facilitated with virtualization and/or automation.
