REST and Periodic Cell Issues

Has anyone experienced any issues when running REST2 with periodic boundary conditions and the solute being scaled is close to or passes through the periodic boundary? Such as getting a FATAL ERROR: periodic cell has become too small for original patch grid (200ns into a production run). If so, is there a way to fix this besides adding center-of-mass constraints to the solute to keep it away from the edge of the box?
