FreeBSD-11 local_unbound stops resolving

I have a reoccurring issue with my recently installed FreeBSD
workstation. The local_unbound dns service ceases to provide dns
entries to the local resolver after some period of time; measured in
many hours or days. I have checked the pf firewall logs and that is
not blocking any traffic relating to DNS that I can detect.
If I re-run local-unbound-setup then local_unbound again resolves. If
I restart the local_unbound service then dns resolution again works.
I cannot see anything in /var/log/messages that indicate that the
unbound service has a problem and the service is indeed running when I
encounter the issue.
We have many other FreeBSD-11 hosts running local unbound and I have
not noticed this issue anywhere else.
This is the resolv.conf file
# cat /etc/resolv.conf
search harte-lyne.ca hamilton.harte-lyne.ca brockley-2016.harte-lyne.ca
# cat /var/unbound/forward.conf
# This file was generated by local-unbound-setup.
# Modifications will be overwritten.
