Basically, if you don't have enough memory, you just don't have enough memory. What FreeBSD does *reduces* the need for memory. If FreeBSD *did not* do it, then you'd need much more memory. > > If the system runs out of memory, the biggest process is killed.

Then, malloc() returns an error indeed. -- Daniel C. Sobral (8-DCS) dcs@newsguy.com dcs@freebsd.org I'm one of those bad things that happen to good people.
