This could be a function of the size of your ESP.

The 5Gbps ESP can handle 256,000 NAT sessions, while the 200Gbps ESP
will do 4,000,000 NAT sessions with a per-second setup rate of 300,000

Of course, it makes little sense to upgrade if you run out of sessions
before you hit the NAT throughput ceiling, so other vendors may be more
commercially palatable.
