There was an error loading the rules

[Spectrum48k]

Logged into my pfsense box, 2.4.1 and found 63 reminders all describing the same issue

can anyone shed any light on this, and how to eliminate the issue?

There were error(s) loading the rules: /tmp/rules.debug:20: cannot define table bogonsv6: Cannot allocate memory - The line in question reads [20]: table <bogonsv6> persist file "/etc/bogonsv6"

a quick look at memory usage tells me no specific issues:
CPU usage 4%
Mem 10%
Swap 0%
Disk 6%
Disk var/run 3%
State table 0%

UPDATE:

Noticed some threads describing same isssue here

SYSTEM > ADVANCED > FIREWALL and NAT >

Firewall Max Table Entries increased from 200000 to 500000

Will see if that fixes it.
