Possibly a scale insect infestation, judging by the number of ants present. They tend to move insects like scale (and aphids, thrips, whitefly, etc) around plants to maximize their production of honeydew, upon which they eat.
Could also be sap rising as the result of a bark-boring insect as well, though ants seldom collect the gum exudate of most plants.
