Hi,

I am having problems with checkpoint restarting for high resolution Carper/McLachlan simulations. For more coarse resolutions I have no problems with checkpoint restarting, nor do I have any problems if the high resolution simulations run for only a few M. But when I do high-resolution simulations until stopped by wall-time and try to restart from checkpoint, I get the following error output :

Any ideas for possible cause and solution to this?
