Comment 4 for bug 1571163

Observations in Vedu's setup which had TCP flows

Flow-export-rate – 100 (Default)
Max men usage was about 52G when active flow count was between 3400000 to 3700000
Mem usage was stable after the flows were decreasing. Observed that it was 52G for more than 20 minutes
Mem usage remained at 52G even when active flow count decreased from 3700000 to 2200000
Mem usage gradually increased from 41G to 47G over a period of 15 mins when the active flow count was in the range of 3000000 to 3500000 (add/deletes were happening with variable of about 500000 flows)

Similar behavior was observed when Flow-export-rate was disabled.

Flow-export-rate – 0
Max men usage was about 44G when flows were between 3400000 to 3600000

This was observed in 3.0.2.0-41~kilo (no private binary)
Mem usage was stable after the active flow count were decreasing. Observed that it was 44G for more than 20 minutes
Mem usage remained at 44G even when active flow count decreased from 3600000 to 2400000
