No, these have very likely different causes.  In your case, you are  
restarting with a different grid structure, so that not all grid  
points can be filled from the data in the checkpoint file.  There are  
two ways to set up the grid structure after recovery: you can either  
specify it manually, either in the parameter file, or by activating a  
thorn which sets up the grid structure before recovering, or you can  
use the grid structure which is stored in the checkpoint file.
