CPU usage spikes to 100% and the WAN disconnects.

Hello all.
I have been attempting to reconfigure my network and this is my first time using OPNsense, I am using a Protectli FW2B, 2 port vault for this.

Now as the title implies not everything went smoothly.
I installed the device just fine and configured everything, and after placing it in my network everything appears to be running smootly for about 20 seconds, before I start running into the issues.

Network connectivity is fine, all devices connected without issue.
However the device ends up spiking to 100% CPU usage even though its neutral state is around 10-20.
While this happens the WAN connection drops and thus I cannot connect to websites on any devices anymore expectedly.

I am not sure how to debug this and could not find any information anywhere.

This is my current set up;
WAN -> Regular Starlink connection which is connected to the router and not in bridged mode (Yet).
LAN -> TP-Link Deco Mesh.

These issues do not occur when I have WAN connected to the TP-Link Deco Mesh, however in all fairness less devices are connected in that state too.

If any of you have any ideas of what I might be able to try that would be lovely.

Unfortunately still having the same issue, if anyone is able to help that would be great.

Try to identify what process is causing it.

Log into OPNsense ssh and run
sudo top -P

Monitor what is happening with CPU load & usage and what proccess/ess may cause this.

Regards,
S.
Networking is love. You may hate it, but in the end, you always come back to it.
