Yes, I recall doing something like that too. In fact, I had guessed at it based on the entries in /boot/defaults/loader.conf, but it still took me 3 attempts to get it right. Some values can be specified like this: hw.physmem="1G" # Limit physical memory. See loader(8) That doesn't seem to work for MAXDSIZ. I ended up setting it like this: kern.maxdsiz="2147483648" # Set the max data size It would be nice to get somebody to update the FM. Thanks for the reply.
