Practical limit to number of jails on a given host?

I don't know of any hardcoded limits, but I can give you some
specifics of what I know works.

We have production servers running 40 jails.  They perform a variety of
functions from database jails that are constantly busy to batch job jails
that sit idle 99% of the time.

These systems have 16G of RAM, 16 CPUs, and about 200 nullfs mounts.

They run like production-quality stuff should, long uptimes (only rebooted
for OS upgrades) and very little maintenance or babysitting required.
