rpi2 hangup during poudriere build: lots of pfault wmseg status

I tried to build some ports on a rpi2
(via poudriere) but it hung up:
Ethernet and normal console use. (Note:
the root file system is on a USB SSD
and the swap partition is also on that
USB SSD.)

But ~^b worked for getting to the db>
prompt on the console.

From there a ps suggests that it got hung
up in pfault activity. (Possibly insufficient
RAM+swap-partition space?) But it is not
clear to me that it should end up hung up
vs. killing processes or other such.

At one point before the hangup top -CawPores
showed:

Mem: 8308K Active, 363M Inact, 11M Laundry, 168M Wired, 88M Buf, 253M Free
Swap: 1536M Total, 1244K Used, 1535M Free

Sometime before it hung up there was:

# poudriere status
SET PORTS   JAIL         BUILD                STATUS         QUEUE BUILT FAIL SKIP IGNORE REMAIN TIME     LOGS

The end of the poudriere output looked like:

. . .

(It looks like a rpi2 does not build its own
sysutils/u-boot-rpi2 .)

The world and kernel were head -r326192:

FreeBSD 12.0-CURRENT  r326192M arm
FreeBSD clang vers 5.0.0svn)

(M is mostly from some powerpc64 and
powerpc material: I build the same
source for everything generally.)

/usr/ports for the ports build was at
-r455204 (last before FLAVORS being
enabled).

I historically have not built ports on
a rpi2. So this is not a comparison with
past results.
