FreeBSD and other 4.4BSD derived OSes don't include the space consumed by mmap'ed files (except the one being execed) in the 'SIZE'. The virtual size as reported is the sum of text+data+bss+heap+stack. This is a "bug" of sorts, but is difficult to fix. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
