Error causing machine to go into endless loop

[Jerry]

FreeBSD 12.0-RELEASE-p10
samba 4.8.12

Lately, my machine has started display the following on screen in a
continuous, rolling manner. I am unable to regain control of the PC and
am forced to do a hard reset, I am unable to remotely access the PC
when this occurs.

This is a truncated version of what is displayed:

Oct 21 05:00:00 scorpio nmbd[77557]:   nmbd_subnetdb:make_subnet()

This just constantly rolls on-screen until I restart the PC.

I have no idea why this is happening or how to debug it since I cannot
regain control without rebooting.
