Description (partial)

invalid traffic numbers inserted from plan files skew graphs

This is a regression from 5.4.  In a very few plan files which Cox uses, some traffic measurements contain large negative numbers which throws off aggregate calculations and makes graphs unreadable for specific time periods.  I will attach a few plan files which show this.  The 5.4 ml_insert_plan tool replaces negative traffic numbers with null.  MATE Design similarly displays negative traffic numbers as n/a.  mate_convert shows the negative numbers.  An excerpt from a Cox plan file, using mate_convert:

In Cox's case, the plan files are from March 14, 2013.  On 3/14, a few plan files had this problem across many interfaces.  I have not checked all plan files.  The plan files are version 5.3.

The collector is incorrect in generating plan files with negative traffic numbers.  This is a separate issue.  Hopefully already fixed.

This problem is severe for customers wishing to migrate older data to ml6+ w/Informix using ml_insert_plan.  There is probably a
