Cannot define table bogons

[jahonix]

php: : New alert found: There were error(s) loading the rules: /tmp/rules.debug:170: cannot define table bogons: Device busy pfctl: DIOCADDRULE: Device busy The line in question reads [170]: table <bogons>persist file "/etc/bogons"

?
I haven't done a thing on the gateway at that time.
Any idea what this might have triggered?

Going to report further after reboot…</bogons>
