System Log error

[zkab]

When I boot the system I get this in Status/System Logs/System/General:

Mar 21 16:43:16 php-fpm 74732 /rc.newwanip: The command '/usr/local/sbin/unbound -c /var/unbound/unbound.conf' returned exit code '1',
the output was '[1521646996] unbound[4934:0] error: bind: address already in use [1521646996] unbound[4934:0] fatal error: could not open ports'

Should I take any action ?
