login.conf used to allow unlimited datasize for the 'daemon' class. That was changed to cap at 4G (IIRC that was a prerequisite before we were allowed to bump MAXDSIZ but I don't remember all the details now). This affects things started from rc - the things particularly likely to run into memory limits here are fsck, mounting mfs filesystems, maybe also running dump or restore from single user mode - also ports daemons, though in most cases we now provide a separate /etc/login.conf.d/daemonname file which raises limits where needed. If you have plenty of RAM you may want to bump that value.
