On that note, can someone explain the difference between the fragment setting 
and the min_average size setting?  We have had this overflow issue when setting 
the fragment size to 2M and the min_average to 10M or larger.  If I set the 
fragment size higher than 2M the traffic server performance falls off a cliff 
or stalls out completely. 

At the moment I have both set to 2M and have not seen the issue resurface 
although it's too early to tell.

_stats reports that I have a max of 1M direntries with the above config.
