Well according to "limit" it was 524M. I don't know how that relates to the
kernel limits you see in /boot/loader.conf. It may be the same thing but being
lowered by something in the startup scripts or it may be unrelated.

If it couldn't allocate the shared memory it wanted it wouldn't start up.

I'm skeptical that you can trust ps's VSZ reporting at this level of detail.
On some platforms VSZ includes a proportionate share of its shared memory or
might not include memory allocated but not actually written to yet (due to
copy-on-write).
