It can be one or more of many things. Let me mention my own recent "pilot
errors" (stealing William's name for it):
1. I did "freebsd-update upgrade -r ...". And left the box live like that
for quite some time. Then I finally decided to indeed go through the whole
upgrade game, and got the box messed-up as a result (with libraries
everything bases on missing, like libc).
2. I had hardware (in my opinion) trouble mess things for me once. It must
have been badblock (no, I don't have zfs on that box), which cut part of
my filesystem tree. This can create big mess if you hit it during upgrade.
And I join someone's opinion that yours may be hardware problem (you just
push the box over the edge during massive build).
As a "band-aid" solution, I would remove any parallel flags from build.
But if I have this happening to one of my boxes I would do this. Take
different machine that can permanently replace functions of this one.
Clean build the system you need on it (be it 10.3, or 11.0). Migrate
everything to this new machine from box in question. Once all works on
replacement box and it is in production for 1-2 Months, wipe the original
box, install new system on it and give the box real stress test to see if
you can rule out hardware, then roll out this hardware into production (as
something else). Alternatively, if you have small shop with no spare
machines, back everything up, shut the machine down, pull original drive,
and stick in new drive (do all minor hardware tricks like re-seating
memory, extra cards etc), install system, and install all what machine
had, and restore users and data from backup.
