FreeBSD10.3-RELEASE. Kernel panic.

Tue Oct 11 04:02:36 UTC 2016

Hello. I have problem with "FreeBSD nas 10.3-RELEASE FreeBSD 10.3-RELEASE
#0: Fri Oct  7 21:12:56 YEKT 2016     nas at nas:/usr/obj/usr/src/sys/nasv3
 amd64"

Kernel panic is repeated at intervals of 2-3 days. At first I thought that
the problem is in the hardware, but the problem did not go away after
replacing the server platform.
