The client tracking implementation wasn't desinged for large number of unique clients.
This is quite fine for appliances with 100's or few 1000's of clients, but it struggles both memory footprint and compute load when the appliance is part of the NTP pool project which can subject it to 1-2 million unique clients per day.
Mitigations are in place (limiting to 50000 clients, etc...), so considering this issue an enhancement not a bug.
