Dear all,

I'm experiencing a behaviour I don't expect.
When running FreeBSD head on a RPI B+ without swap space
it shows the following behaviour on the console:

[bsd10:~] tuexen% dd if=3D/dev/zero of=3Dlarge_file bs=3D1m count=3D1024
Nov 12 11:22:16 bsd10 kernel: pid 666 (sshd), uid 1002, was killed: out =
of swap space
Nov 12 11:22:19 bsd10 kernel: pid 606 (thttpd), uid 65534, was killed: =
out of swap space
Nov 12 11:22:24 bsd10 kernel: pid 316 (devd), uid 0, was killed: out of =
swap space
Killed
[bsd10:~] tuexen% Nov 12 11:22:27 bsd10 kernel: pid 676 (dd), uid 1002, =
was killed: out of swap space
[bsd10:~] tuexen% uname -a
FreeBSD bsd10.fh-muenster.de 11.0-CURRENT FreeBSD 11.0-CURRENT #10 =
r290676: Wed Nov 11 20:23:53 CET 2015     =
tuexen@bsd10.fh-muenster.de:/home/tuexen/head/sys/arm/compile/RPI-B  arm
[bsd10:~] tuexen% ls -l large_file=20
-rw-r--r--  1 tuexen  tuexen  584056832 Nov 12 11:22 large_file

Shouldn't I be able to use dd to generate an almost arbitrary large file =
(limited
by the filesystem, not by the memory)?

Best regards
Michael=
