It seems to be triggered by pfBlockerNG. It worked just fine in the old verison. But after updating to 2.8.0 a few days ago its been having this error a lot!

It has 32683 MiB of RAM in the box

I had disabled PFBlocker and didn't have the error when restarting unbound.

Turned PFblocker back on. Had it update. And as soon as it was done, when I go back to the dash I see a crash notice....

```
Crash report begins. Anonymous machine information:

amd64
15.0-CURRENT
FreeBSD 15.0-CURRENT #1 RELENG_2_8_0-n256081-401ec5f685b9: Wed May 21 23:53:51 UTC 2025 root@freebsd:/var/jenkins/workspace/pfSense-CE-snapshots-2_8_0-main/obj/amd64/0q9vjGjc/var/jenkins/workspace/pfSense-CE-snapshots-2_8_0-main/sources/FreeBSD-src-RE

Crash report details:

PHP Errors:

No FreeBSD crash data found.

```

I also noticed in the PfBlocker log...
`Database Sanity check [ FAILED ] * These two counts should match! *

So aftering giving stuff in ChatGPT to lookout from that error and my log PlfBlockerNG Update.log

It told me...
```
You’re loading very large lists:

BLP_Malware: 435K entries

BLP_Phishing: 190K entries

BLP_Redirect: 108K entries

Total count: likely over 1.5 million entries```
So I disabled those...

Then after a while it had me go into:
Go to:

System → Advanced → System Tunables
Then:
Add or edit:
Tunable: php_memory_limit
Value: 2048
Description: (“Increase PHP Memory”)
```

So I did that. And rebooted the router..

I then noticed in `/conf/config.xml` that I had a new thing
```
<sysctl>
<item>
<tunable>php_memory_limit</tunable>
<value>2048</value>
<descr><![CDATA[Increase PHP Memory]]></descr>
</item>
</sysctl>
```

And then I rebooted.. And nothing changed..
So it said to move it from a to <sysctl> to a <system>

So I removed that thing from the bottom from the system tunable I made.
And then moved up into the system area at the top and added in

```
...
</user>
<nextuid>2010</nextuid>
<nextgid>2000</nextgid>
<timezone>America/Chicago</timezone>
<php_memory_limit>2048</php_memory_limit>
<time-update-interval>300</time-update-interval>
<timeservers>162.159.200.123 time4.google.com time5.facebook.com time.cloudflare.com time.google.com pool.ntp.org</timeservers>
```
I put that memory limit just in that area of that system then...

Then I ran `/etc/rc.php_ini_setup` so it regens the php config..

And now when I run
`php -i | grep memory_limit`
I get
`memory_limit => 2048M => 2048M`

Now to see if I still have that error if I try again with my pfblocker update...

After doing all that I now learned..

System > Advanced > Miscellaneous > PHP Settings is exactly what sets the <php_memory_limit> tag inside the <system> block of your config.xml

So the issue that looked like an kea2unbound issue. That this error it made should maybe to editing to say to go into your System > Advanced > Miscellaneous and raise the PHP Memmory Limit ....

Project changed from pfSense to pfSense Packages
Category changed from DNS Resolver to pfBlockerNG
Priority changed from Very High to Normal
Release Notes deleted (~~Default~~)

What you should be doing here is setting pfBlockerNG to use Unbound mode if you are loading a lot of large lists.
