The respective AFD status reported back that it is
stopped when the MP thinks it should be running and
no AFD shutdown diagnostic exists. This diagnostic
will be logged in the active buffer and then
automatically cleared. This diagnostic could be
caused by intermittent communication problems
from the AFD to the MP, or due to misbinding
