It is nearly impossible to help you without any details given.
What is the load your servers process? Do they perform some heavy networking? Do you use GENERIC kernel or not? Do you use IPv6? IPSEC? NETGRAPH? Is ZFS involved?
Do not be afraid to supply as many information as you can.

FreeBSD 10.3 official support ends April 30, 2018: https://www.freebsd.org/security/security.html#sup
10.4 has been released half a year ago, 11.1 nine months ago. Does this problem reproduce with those releases? If yes, please show exact tar commands that lead reboots.
Have you tested hardware to rule out hardware problems? Start with memory testing.
Also, for dumpdev in /etc/rc.conf please use exact swap partition name like dumpdev="/dev/ada0p2" or "/dev/ada0s1b" instead of "AUTO".
Feeback timeout over 2 years. Since then, FreeBSD 10.3 went EoL.
