Summary: Let $\Omega $ be a bounded, strongly pseudo-convex domain with smooth boundary in $\mathbb{C}^n$. Suppose that $h$ is an analytic function defined on an open set containing $\overline{\Omega }$. We show that the principal submodule of the Hardy module $H^2(\Omega )$ generated by $h$ is $p$-essentially normal for $p > n$.
