PfSense 2.4.4 LAN interface stops routing traffic - stops working after some minutes, sometimes hours

[e066377]

I setup IPsec vpn with 9 Phase 2 tunnels that requires to NAT LAN to a public static IP.
Although the connection is stable, Phase 2 tunnels stop working sometimes after few minutes, sometimes after 10+ hours.

People had the same problem before : https://forum.netgate.com/topic/98893/pfsense-2-3-lan-interface-stops-routing-traffic-stops-working-after-2-or-3-day

And it was fixed with 2.3.1, it think it was a solution by disabling all but 1 CPU.

My vm shows:

[2.4.4-RELEASE][admin@pfSense.localdomain]/root: dmesg | grep cpu
cpu0: <ACPI CPU> numa-domain 0 on acpi0
cpu0: <ACPI CPU> numa-domain 0 on acpi0
cpu0: <ACPI CPU> numa-domain 0 on acpi0
cpu0: <ACPI CPU> numa-domain 0 on acpi0
cpu0: <ACPI CPU> numa-domain 0 on acpi0
cpu0: <ACPI CPU> numa-domain 0 on acpi0

no CPU id to disable, but 6 identical cores.

How can i have stable phase 2 runnels?

I need help to find a workaround for this problem.

Thanks.
