Unexpected freeze OPNsense web interface

[Alex_1]

Hi, I try up and running OPNsense, but two times I'm faced to the same unexpected freeze web interface. In the evening firewall working fine, but in the next morning console still in the same state, but web interface not responding. Gateway is still pinged.
What happens? What is the best pattern to overcome this freeze?

When I try to reboot my OPNsense, I see a millions of this message, IP address of this message is my gateway. What happens?

maybe I have understanding, need to add another VLAN to LAN interface than VLAN in WAN
this is test system and I don't tune it accuracy, this is a result
