If you have holes in the phys map, real memory should reflect these holes. Avail memory is the total memory as reported by EFI map. Verify all that by looking at sysctl machdep.efi_map output. > > On Fri, Mar 22, 2024 at 07:54:06PM +0100, Bernd Walter wrote: > > .. > > real memory = 1649265344512 (1572862 MB) > > avail memory = 1057138888704 (1008166 MB) > > .. > > > > I suspect address space issues, but don't know for sure. > > Changing NUMA nodes per socket in the BIOS had an influence to make it > > worse, but not better. > > > > > > Copyright (c) 1992-2021 The FreeBSD Project. > > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > > The Regents of the University of California.
