Any of you guys have experience with small splits/chatter/chip at the heel of your fretboard? The below is over-exposed and over-enlarged to show better but you can see a couple of minor splits or chatter at the heel end between the D and G strings and again at the corner. I assume its from slapping(?) and don't want it to get worse. The straight grain pattern combined with the nature of Spalted wood doesn't help here I'm sure.
Epoxy?...

You could stabilize it with epoxy. You’d have to be careful when you apply it though (obviously with the neck off and make sure to remove excess because it would be hard to sand with the frets installed). You must be really physically slapping.
