I cannot say anything about the traffic or load it had, but I doubt it was much. The crash did not appear again (yet) after upgrading to 10.3-p7: --- Mon Sep 19 02:55:28 CEST 2016 FreeBSD ahfwx.aei.uni-hannover.de 10.3-RELEASE FreeBSD 10.3-RELEASE #0 r297264: Fri Mar 25 02:10:02 UTC 2016 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 panic: page fault GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
