this is the end of a ktrace: 3857 ps CALL open(0x80146de1b,0<O_RDONLY>,<unused>0) 3857 ps NAMI "/proc/sys/vm/min_free_kbytes" 3857 ps RET open -1 errno 2 No such file or directory 3857 ps CALL write(0x2,0x80146e350,0xb0) 3857 ps GIO fd 2 wrote 176 bytes "Error: /proc must be mounted To mount /proc at boot you need an /etc/fstab line like: proc /proc proc defaults In the meantime, run "mount proc /proc -t proc" " 3857 ps RET write 176/0xb0 3857 ps CALL exit(0x66) That file is referenced in proc/sysinfo.c and used in function meminfo(). I've re-checked: all commands that use meminfo() fail. There is no directory /proc/sys/vm in either the FreeBSD-kernel 10.1-0-amd64 (jessie-kfreebsd) nor in 10.3-0-amd64 (sid). The reference to /proc/sys/vm/min_free_kbytes apparently was introduced with your commit f65d2815913f5d8ff4156384dceb160edd6da812 titled "Imported Upstream version 3.3.10". Carsten
