Yes, 2G - 1 is the maximum size a signed int can hold ... mind you, any program needing more that 2G of memory really should be implementing on-disk storage of data for itself. > > >You can also tune this at boot time by adding them to the file > >/boot/loader.conf. e.g. > > > >kern.maxdsiz="(256*1024*1024)" > > I added this (though it was actually 1024*1024*1024) to /boot/loader.conf > and also /boot/defaults/loader.conf, and booted the GENERIC kernel. Yes, I just copied the numbers from what was given above - I should have substituted 1024 or more in there. > The limits were still the old ones (i.e.512M).

It may be the case that you cannot specify the value like that in loader.conf, in which case we must do the math ourselves.
