--- Comment #1 from Kristof Provost <kp at freebsd.org> ---
Yeah ... you're out of memory, there's not much we can do in that situation.

The allocation code for tables deliberately does not try forever to get memory
(i.e. it allocates with M_NOWAIT), because if it did you could lock up pf
accidentally by trying to allocate a far too large table.
A consequence of this is that if you're under heavy memory pressure you're
going to fail to allocate, and fail the reconfiguration.
