I don't understand your 1.5 GB reference.

I think you set the kernel maximum in /boot/loader.conf and can then set
per-user limits up to that value in /etc/login.conf.

IIRC the stock unmodified kernel limit is 512 MB per process, and the
login.conf default is the same 512 MB. Login.conf can not override the
kernel. Something like this needs to be added to /boot/loader.conf:

kern.maxdsiz="3G"	# think this is the absolute system per-process limit
kern.dfldsiz="3G"	# think this is the default per-process limit
kern.maxssiz="128M"	# stack size
