I got this warning when back annotating an sdf file. What exactly does it mean and will it cause any problems?

ncelab: *W,SDFNL2 (,35120|7): The sum of the two annotated limits to $setuphold, $recovery or $recrem timing checks are less than zero for instance :UUTreg[6] , setting negative limit(s) to 0 <...sdf, line 17994>.
