@bingo600:

I just got the same error today on 2 independent 2.4.2-p1 boxes There were error(s) loading the rules: /tmp/rules.debug:35: cannot define table bogonsv6: Cannot allocate memory - The line in question reads [35]: table <bogonsv6> persist file "/etc/bogonsv6" @ 2018-04-01 14:49:30 It has to be the bogon file that has increased in size , as i haven't touched one of the boxes in 2 weeks I have tried to increase from 200K to 500K entries (both are 8G Ram machines) Lets see if i keep on getting the errors Weird … still get the errors w 500K entries Nope 500K entries solves it In "System -> Advanced -> Firewall & NAT" I increased the below from 200K to 500K

MIght be a good idea to do a reboot after the increase. /Bingo

Just to help other people, you cannot see the full post, with the image showing the needed details, unless you're logged into the forum with a member's creds so here's where you change it if you happened upon this thread via a search engine like I did: System > Advanced > Firewall & NAT > Firewall Maximum Table Entries

This bit of info helped with my issue as well. I don't have but a handful of firewall rules so I didn't think it was anything I did. Furthermore, I hadn't seen the errors until after the upgrade to 2.4.3. At first, I was seeing the errors nagging about the couple rules I've created but, after a reboot, it was throwing the errors about the bogon network rule in the table and I know that's a factory rule; not one I customize. So, watch your red herrings…

I think when the developers upped the size of the bogon networks file, they should have at least recommended the changing of aforementioned setting. I don't think changing it for the end user is a good idea as you never know what hardware the OS is running on but a warning would have been nice; that's just my two cents.
