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.
