I have the same problem.  The build did not finish successfully; it
didn't even start.  Simply running `poudriere ports -u` (basically a
wrapper for `git pull --rebase`) was enough to render the system
unusable.  Apparently every pipe(2) call by a privileged process returns
ENOMEM, which means no shell script more complex than hello world can
run, and you can't ssh in because sshd fails to set up the pipe it uses
to talk to the privsep child.

I also have a bunch of these on the console:
