Comment (by hinder):
If you recover on a different number of processors, then the messages are irrelevant - you already know that the system has to check other files. At most, I would think a single message along the lines of "Warning: recovering on a different number of processes is often slow" would be all you would need. If you are NOT recovering on a different number of processes, then the messages indicate a serious unexpected performance problem. There is the related issue of this happening because of Carpet choosing a grid structure at runtime different to what was in the checkpoint file (see http://cactuscode.org/pipermail/developers/2010-June/005980.html). I do not know if this has been fixed.
