My pfSense Plus firewall crashed this morning

rameshk

Hi There,
My pfSense+ crashed this morning and restarted. It was working fine before and after the reboot. It's a bit strange as it never happened before. I have attached the textdump file for your review.

CPU: Intel Celeron 3965U
RAM: 8GB
NIC: Intel 6 ports
pfSense ver: 23.05.1
Plug-ins: pfBlockerNG, OpenVPN, Suricata, FreeRadius server

Note: I am using pfSense for a very long time and never had this issue.

Nothing very revealing there.
You do have a lot of link state changes shown in the message buffer but that could have been over a long period?
