Running out of swap can be easily done by normal user privilege. Non-overcommiting system can run important application on the system which has a normal user, because it never lose critical data, even if a user on the system make a mistake. (The application might stop, but it never lose data.) 4.4BSD derived system cannot do this, and have to use different machine for such applications. > And you also haven't bothered to address my other point: In order to > configure a system that guarentees backing store, you need to configure > that system with 8x or more swap then you would a normal > system. 8x or more? That's wrong. It depends. -- soda To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
