I play it safe by using the actual number. On other thing to beware of, whether you set this in the kernal or /boot/loader.conf, is that you cannot go over 2^31-1 because FreeBSD uses a signed int for this value (I tried setting it to 2G once and MySQL refused to start - MySQL AB verified the problem). -- The information contained in this email is confidential.
