FreeBSD Sky23eCao.mydomain 10.0-RELEASE-p1 FreeBSD 10.0-RELEASE-p1 #0 r264294: Wed Apr  9 18:38:56 CST 2014     root@:/usr/obj/usr/src/sys/SKY23ECAO  amd64
>Description:
When I type "netstat -si" in xterm on my physical machine, system crash.
The user is not root, but in group "wheel".

After restart the system, I see the line:
"savecore: reboot after panic: page fault"

And then I try it again in a idle system, and crash again.

It is correct in VirtualBox in which FreeBSD 10.0-RELEASE-p1 runs.
>How-To-Repeat:
I start the system, and launch xterm, 
and then type "netstat -si" in it,
and type enter,
and the system freeze.(maybe it is dumping the kernel)
After 5-10 seconds, system restart automatically.
