I have my system up and running for let's say 10 hours or so where these operations on map ( continuous add/delete) keep happening. Memory keeps growing and goes very high. Eventually at end of test we clear all map entries, memory is reclaimed and is good. It's basically kind of load test. Appreciate your engagement.
