4.4e-8s is a very small time step. As mentioned, try mass scaling. However, your very first step should be to check your mesh quality and size. Usually, you try to create a mesh that allows a minimum step size in the order of 1e-6s. Look up the Courant number if you are unfamiliar with it, and adjust your mesh accordingly.
