Old slices weren't having their totals cary over when NM was reset or reinstalled.  New slices would start out with 0 bytes in their byte counts, then when update was called 10 minutes later, their running byte count would would already be over their max, then the slice would get capped.  New slices that are already running (presumably from a previous instance of NM), should have their byte counts carried over on init.
