When enabling pfblocker I keep getting the following error message. I have already increased the Firewall Maximum Table Entries to 400000 which is more than enough. see below output. any other ideas please?

error:
There were error(s) loading the rules: /tmp/rules.debug:25: cannot define table pfB_Top_v4: Cannot allocate memory - The line in question reads [25]: table <pfB_Top_v4> persist file "/var/db/aliastables/pfB_Top_v4.txt"

@jsbsmd I'd be concerned that it says "Cannot allocate memory". Do you have enough RAM free?

[jsbsmd]

only using 36% of 1gb ram.

@jsbsmd said in errors loading rules after enabling pfblocker:

Cannot allocate memory

Perhaps it's insufficient Table States? Have a look at this thread.

System > Advanced > Firewall & NAT
Set Firewall Maximum Table Entries to 400000 (or just double the default value)

[jsbsmd]

@Stewart , As you can see by my initial post I have set the setting to 400000 and according to the reload, the table is only 265803 in size.

[BBcan177]

That limit needs to be approx 2.5X the size of all alias tables (pfB and any other pfSense / packages included)
Just set it to 2M and forget about it.

[jsbsmd]

That may have done the trick. I will keep monitoring. thanks.
