My figs have stopped ripening–why?

Question

I have had an abundant harvest for the last 2 years and both years at the start of Autumn the tree is still covered in fruit but they stop growing and ripening,they get to about the size of a large cherry and then nothing.
They do not fall off the tree but have to be picked off.
We have had very hot,dry summers and have watered copiously,we have a watering system at ground level,I fertilise and mulch to retain moisture.
The tree is planted in a corner that faces north and east and is protected from the south and west.
