6. After rebooting the device, a memory leak occurs, reaches 98-99% and the router stops responding, it is impossible to access http://192.168.8.1
7. Helps → Custom DNS Server → enable/disable → DNS Rebinding Attack Protection or Override DNS Settings for All Clients, the memory is normalized around 58-60%, this must be done before the memory reaches 95 or more.

I have tested 2 versions of 3.214 beta firmware so far (0413, 0421), I found out that the qca-nss-ecm is disabled by default ? Does this mean that the NAT hardware offload function is turned off by default unless you turn it on manually ?

qca-nss-ecm is disabled if ipv6 is enabled. But almost no NAT performance penalty as the powerful cpu.
As a result, the cpu sirq increse from 0% to 30%.
