We show that if Ω is a vanishing chord-arc domain and L is a divergence-form elliptic operator with Hölder-continuous coefficient matrix, then log k L∈ V M O, where k L is the elliptic Poisson kernel for L in the domain Ω. This extends the previous work of Kenig and Toro in the case of the Laplacian.
