--- Comment #7 from Adrian Chadd <adrian@freebsd.org> ---
ok, I bet my first-touch iterator is biting me. It doesn't skip over the
first-touch domain, so it's possible that you've hit a situation where the
domain 'n' fails allocation, and the per-thread round-robin domain value is
also 'n'.

We'll just have to fix the round-robin iterator routine to take a domain to
'skip' over (and have it ensure that it isn't just a single domain (0) and thus
gets stuck skipping over that. :-)

I don't have any NUMA boxes handy atm but I'll try to come up with a patch to
test.

Thanks!
