    This seems to be an infection that has, not yet, been resolved. They are very drought tolerant, but will not tolerate wet soils. This leads to infection, somewhat quickly.

    I would treat with a fungicide, and prune out any growth that is completely dead.

    Be sure to only water during times of severe drought, or at the very least, make sure that the soil dries out thoroughly down to about 4 or 5 inches between waterings.

    Here are some articles that will help:

    If it is tree borers, it is very hard to kill them because they are inside the tree doing extensive damage. It is usually best to replace the tree.
