Premature Dropping of Leaves on Well-Established Mulberry Tree

Question

After a very abundant fruiting and beautiful large green leaves from April/May on, our long well-established mulberry tree is now suffering (starting early Aug. ) with massive leaf loss, and remaining leaves are looking wilted and brown, shortly due to fall also I fear! We live in southwest France and have not had much rain but other mulberry trees nearby show no sign of problems of leaf loss so early. There are vertical cracks in the trunk, but they have been present for years only opening up as the tree has grown. HELP! What can we do?
