I would wager you started the simulation with her in this exact position. Everything I see there says 'collison error', as in follicles penetrated the cushion geometry (assuming the cushion is set as a collision surface. You also could have run into the cushion having so many polygons that the sim simply failed). Another possibility there is having the hair groups sharing vertices. Same effect.

And isn't 80 verts per follicle awfully high? Most of the settings I've seen have ranged in the mid teens to very low 20's.
