Something else you might try, in lieu of these changes, is to drop maxusers to 128. This frees up a lot of KVM. The auto-sizer maxes out at 512MB, and past 1GB the page tables start consuming a non-trivial amount of memory. If you need to increase maxfiles or mbufs, you can tweak those manually using loader and/or sysctl. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
