this signals tha the dynamical matrix, as calculated by the phonon code, is not hermitian. Since hermiticity violation for very small elements of the dynamical matrices is not a problem, both absolute and relative values of the violation are printed. In this case, it does not seem to be irrelevant. The main reason for violation of hermiticity is insufficient convergence of the phonon self-consistency.
