I would first check for interpenetrating geometry. MAybe try reducing the penetration threshold on the bullet solver. Are you by any chance using a drag dop in the glass simulation? I had something similar where the drag node caused my bullet sim to go haywire. You could also try whacking the substeps on the solver.

thanks for your reply.

I just tried what you suggested me

pieces are still boucing on the fluid  surface.

I don't understand why.
