title: Limitations and failures of the Layzer model for hydrodynamic instabilities.
abstract: We report several limitations and failure modes of the recently expanded Layzer model for hydrodynamic instabilities. The failures occur for large initial amplitudes, for stable accelerations, and for spikes in two-fluid systems.
