--- Comment #34 from Mark Millard <marklmi26-fbsd@yahoo.com> ---
FYI:

With vfs.nullfs.cache_vnodes=0 I instead got the
"failed to reclaim memory" type of failure, losing
control because of what had been killed.

So the nullfs VNODE caching is not a fundamental
part of the problem. nullfs VNODE caching can
contribute to variability in the failure details
since it changes the memory use pattern, or so
it appears.
