I had that problem for several years. I read on a web site (I think
Pollinator's) that it was a sign of inadequate pollination, leaving
the fruit weak and open for the fungus that follows. Due to clear
cutting of forest around our neighborhood several years ago our wild
bee population was way down. Since putting a beehive in my back yard
at Christmas, I have not had the problem.
