V 3.2.0 with pfsense 23.01 RC 20230202
-
Ran into the same problem with the memory usage.
Not sure if the other issues I had with 23.01 came from PfblockerNG but IPv6 had some weird issues which I couldn't resolve.
For now I rolled back to 22.05. -
@pfsjap I am now back at 23.01-RC1 and have applied the patch from jimp sucessfully.
This has solved my issues with the long reloading (at least to a certain point).
The patch has indeed reduced the reload time from ~16 hours (23.01 without the patch) to arround 2,5 hours (147 minutes exactly).
While this is a significant improvement, the reloading times are still way slower than on 22.05, where a full reload normally is faster than 20 minutes.But the much worse issue for me still persits:
After the full reload of all the block lists, unbound gets restarted, but then gets killed again because it has used all of the available memory.So for me the memory issues could be tracked down to unbound, see:

@greenflash Is your DNSBL Mode set to Unbound Mode? Changing to Unbound Python Mode may help.
I have 1GB RAM on Netgate 1100 with 260MB set to RAM disk. Not that many feeds, though.
-
@pfsjap currently it is already set to Unbound Python Mode. I do have 16GB of RAM installed, on 22.05 the whole system never used more than 5 GB at maximum.
I have not a changed any of my block list feeds since the upgrade. Therefore there has to be some kind of an issue with memory management (or even a memory leak) regarding pfblocker and unbound on 23.01.
-
@greenflash Ok, hopefully you'll get help with this.
-
@greenflash I worked on Unbound quite a bit over the past month tracking down memory-related issues.
What does your DNSBL setup look like?

No change. Confirmed the patch applied. Updated to 23.01.r.20230202.1645 from 23.01.r.20230202.0019 yesterday and confirmed successful pfBlockerNG force reload all, before and after the update, and before and after applying the patch, with success as long as Wildcard Blocking (TLD) is unselected.
The "TLD finalize.." step seemed to take just a couple of seconds on 22.05 with my hardware, so I don't believe it's an issue of my not waiting long enough (especially now since the patch seems to have corrected a typo to enforce timeout in 15 seconds).
Let me know how else I may be able to help.
Finally got time to upgrade to 23.01-RC and can confirm that with Wildcard Blocking (TLD) feature enabled the update/reload process hangs on "TLD finalize..."
There's a Redmine ticket for this issue: https://redmine.pfsense.org/issues/13884 -
@jimp's patch just got applied to an updated pfBlockerNG v. 3.2.0_1. (Thanks!) That appears to have been the only change.

Using the latest pfSense RC :

The /tmp/dnsbl_tld_remove file - the list with TLDs to remove is 37000+ lines.
The /var/unbound/pfb_py_data.txt.raw file 133608 lines[edit]
From what I make of this : each of the 37000+ lines is checked (grepped) with every line in the 133608 file.
So, 37000 times 133608 'greps' to be executed.
That's huge ....And I have only one dnsbl feed - with "133608" dnsbl entries.
[end edit]I copied both files to /root/ and repeated the command 'on the command line'.
This command is great to max out one core, 100 %, and it will take minutes if not hours to complete.pfblockerng-devel does this with PHP handling the return (output). That will make things even worse.
49 degrees and rising. Of to the kitchen, looking for some eggs.
I guess not using (unchecking) Wildcard Blocking (TLD) is the best option right now.

I'm not using TLD Whitelist
My DNSBL Mode is set to "Unbound python mode" and as pfBlockerNG states: "TLD Whitelist is not utilized for Unbound python mode! Use DNSBL Whitelist instead."
The main problem is when Wildcard Blocking (TLD) is enabled. -
@emikaadeo
You're right :That's the one :

I believe mine is now having the same issue with my upgrade to 23.01-Final. I manually did a reload and it's at 20 minutes, stuck on "TLD finalize."
I did have an error: On it's first boot I got a banner about this extensive error: https://pastebin.com/aj8q4Mjw than that, It seems to work fine and appears to be passing traffic across 2 VLAN and 1 WAN.
-
This happened to me today as well and likewise disabling Wildcard Blocking (TLD) worked around it. grep was stuck at 100% CPU utilization for several minutes otherwise.

Andy Fix for this? Except disabling Wildcard TLD blocking
