Your current run is using mdrun -npme -1 (the default). Probably the
former run was also, but zero was chosen by mdrun. The latter was
recorded in the checkpoint file, and now mdrun is telling you that there
may be some degree of discontinuity between the runs if you were to have
changed something else that would lead to zero not being chosen this
time (e.g. running on more nodes). If you specify the same suitable
value each time for -npme, this warning will never occur.
