can somebody throw more light on this? How it is possible (without a bug) that for exactly same set of IPs, at time IPSET HASHSIZE remains at 1024 and at times it increases to 2048?
As a workaround I am running the show setting HASHSIZE as 16384 at times of IPSET creation itself, and till now (its more than 4 days) the issue has not repeated. But this need to be addressed, right?
