PFBlockerNG 2.1.1_2 Memory Errors

[rajl]

I'm having constant "out of memory" errors related to the latest release of PFBlockerNG.  An example error message reads:

/usr/local/www/pfblockerng/pfblockerng.php: PHP ERROR: Type: 1, File: /usr/local/pkg/pfblockerng/pfblockerng.inc, Line: 3874, Message: Allowed memory size of 536870912 bytes exhausted (tried to allocate 72 bytes)

I have a really simple PFBlockerNG ruleset – block all incoming connections except for IPv4 and IPv6 connections from the United States + the ad-blocker built into PFBlocker.

I've seen other people on this forum report similar problems, but their solutions don't seem to work for me.  For example, I have already increased the setting for Firewall Maximum Table Entries from 2000000 to 4000000 (see e.g. https://forum.pfsense.org/index.php?topic=102470.msg643960#msg643960) but continue to get memory errors.

Any other ideas?

This is also related to the MaxMind db issue. But fixing this in that part of the code isn't so simple as BBcan177 is away at the moment.

Check the selection of countries in the GeoIP tabs, someone reported that the selection was inverted at some point.

[rajl]

What should I be looking for?  I only have one country selected (United States) and I did invert the rule (i.e. block all inbound connections except from U.S.).  Are there any solutions other than to change the maximum number of table entries?  I have  8GB of RAM installed in my PFSense box, so the idea of running out of memory is a bit flumoxing as by all measures, I should have more than enough.

Thanks

[RonpfS]

That was just to make sure that nothing got crooked in the config. One users reported that the selection was inverted somehow on his setup.

The only fix will come from BBcan177, but for now is doesn't have affordable Internet access somewhere in the middle of the sea. :(

[RonpfS]

The problem seems to be related to i386 installation.
The fix is to edit /usr/local/pkg/pfblockerng/pfblockerng.inc  (Diagnostics/Edit File)
go to line 236

change```
pfb_global();

// DNSBL Lighttpd HTTPS Daemon (Scans Lighttpd dnsbl_error.log for requested https domain names)
if (isset($argv[1]) && $argv[1] == 'dnsbl') {

to```
pfb_global();
ini_set('memory_limit', '300M');

// DNSBL Lighttpd HTTPS Daemon (Scans Lighttpd dnsbl_error.log for requested https domain names)
if (isset($argv[1]) && $argv[1] == 'dnsbl') {

I tested with 128M, 200M and it fails
256M succeeds, but BBcan177 recommends using 300M. You might need more depending on your system.

So for i386, the default is 128M so very low, it should be 256M or more depending on you setup.
For amd64 system, the default is 512M, so you might need to bump it to 640M or 768M.

after the modifying the file, go to shell and run

php /usr/local/www/pfblockerng/pfblockerng.php dc

Once this succeed, you do not need to re-run the dc command. The GeoIP db will change next month.

[Gerard64]

Thanks for the tip and help!
I changed the file like you wrote and i run the command in a putty terminal on the router now it hangs like 5 minutes on:

Yes it takes 5+minutes to complete

Try increasing to 400M, 500M up to 750M

[Gerard64]

Thanks  RonpfS ..!
After I set it to 500M it worked.

[Qinn]

@Gé:

Thanks  RonpfS ..!
After I set it to 500M it worked.

Thanks @RonpfS setting the memory_limit on line 236 to 300M fixed it, strange that @Gé needed 500M?

[Perforado]

For me i needed even 500M didn't work :/ 640M worked for me.

[RonpfS]

@Perforado:

For me i needed even more as 500M didn't work :/ 768M worked for me.

Which version of pfsense?
x386 or amd64 ?
how much ram ?

[Perforado]

CPU: Intel(R) Atom(TM) CPU  C2558  @ 2.40GHz (2400.06-MHz K8-class CPU)
RAM: 8192MB

pfSense 2.3.3.a.20160803.1621
pfBlockerNG 2.1.1_2

[RonpfS]

Well on amd64 the default is 512MB.

/var in Ramdisk ? getting full ?

[RonpfS]

@oswoldy:

Ok, while the php /usr/local/www/pfblockerng/pfblockerng.php dc command works, the cron jobs are still crashing and giving errors, I am currently at 2GB limit and climbing.

If you run the dc command, it changes the GeoIP database, you have to run a force reload after the dc complete.

Also check diagnostic system activity to see if there isn't something unusual.
Look at the System log for hints on the failure mode.
An can you post the portion of the pfblockerng.log file where you have failure.

Ok, I ran the dc command, followed by a force reload, no different. If I remove pfB_NAmerica_v4 then it works fine, crash report is:

I have reduced the limit back to 500MB as increasing it wasnt making a difference, the dc command still completes but not a force reload or CRON.

Once the dc command complete, the MaxMind database is created, so you do not need to re run it.

What about the pfblockerng.log ? What are the symptoms ?
Maybe raise it to 640M or 768M?

I started a thread up over in the pfblocker posting and just letting everybody know that I'm also experiencing very similar memory issues.

Thismorning when I logged in, I also had a pfsense crash report with the following:

How I solved my problem:

My pfSense config:

• Version: 2.3.2 (amd64), running on VMWare 6
  – Snort
  -- pfBlockerNG
  -- OpenVPN
  -- Open-vm-tools
  -- DHCP Relay
  -- Quagga OSPFd with another 2 pfSense.
• ~3000 users simultaneously
• 2 x 100 Mbit uplinks
• 16 GB RAM
• 80 GB SAS
• CPU Type: Intel(R) Xeon(R) CPU E5-4620 v2 @ 2.60GHz
• 16 CPUs: 8 package(s) x 2 core(s)
• 8 Interfaces, including WAN
• routing, filtering and relaying dhcp to 16 branches over MPLS, WiMax and fiber
• Load balance and failover
• QoS with Traffic shaper

1. Updated Firewall Maximum Table Entries: 4000000 -> 8000000
   1.1) Reboot
2. Edited /usr/local/pkg/pfblockerng/pfblockerng.inc and set memory limit to 500M
3. Executed php /usr/local/www/pfblockerng/pfblockerng.php dc
4. It's alive.

Thanks to all involved.

The php memory should be 512M by default, so setting it in the inc file to 400M might not help.
Did it fail without any fix to the inc file? Can you try setting the limit to 640M or 768M?
What do you have for Firewall Maximum Table Entries?

You will need to run  php /usr/local/www/pfblockerng/pfblockerng.php dc from the shell.

[RonpfS]

For those with failed installation. Verify that /var isn't full. The MaxMind database is huge so if you are using a RAM Disk, it might eat up memory that is needed for the pfblockerng.php.

If disk space is running low, BBcan177 suggest to delete the /var/db/pfblockerng/deny and /var/db/pfblockerng/original folders before installation to free some disk space. This means it will need to redownload all IP feeds after installation.

Check pfblockerng.log, the system log, Dashboard for crash report, Status Monitoring System Memory.

Post relevant debug info here.

I'm going to have to do a bit of work this weekend on this and see more.  I can try it and see what happens, but I'm getting concerned about reaching my 2gb memory limit.  I can add more memory, but that requires me to go to the store and I'm kinda lazy…..and cheap.  :)

Interesting that I too have a similar setup to the one user above.  I'm running it on vmware esxi with Snort (disabled) and OpenVPN.  Granted, I don't have nearly the hardware or setup, but it's interesting that we're both running vmware.

[wiz561]

OK…  Now maybe I'll try what others suggested...  :)

I wiped and reinstalled pfsense tonight and pfblockng is still coming back with that crash and memory errors.  I know others said to adjust the memory but I thought I would give this a try.  Unfortunately, it failed.

I also had issues with php-fpm having high utilization....so I'm hoping that the wipe/reinstall fixed the issue with that.  Time will tell.

[RonpfS]

What about posting pfblockerNG, system log, crash report, screen shot of system activity, etc, so we can see what is happening on your setup?

The crash report you posted earlier tells me you have under 400MB defined.

[Perforado]

Temporary Fix for

Failing with memory exhaustion:

edit /usr/local/pkg/pfblockerng/pfblockerng.inc as discussed above:

pfb_global();
ini_set('memory_limit', '640M');
...

cp /etc/rc.php_ini_setup /etc/rc.php_ini_setup.BACKUP

There is probably a setting (memory_limit?) we can configure in the System/Advanced/System Tunables that will do that for you. But it may require a reboot.

The fix for the inc file is specific to pfblocker and shouldn't be needed once BBcan177 change the code.

pfB_Top_v6 was about 13000-ish before as far as i recall.

I've been busy the past couple of days and blowing it away and restoring the config was pretty simple.  I'm going to try to work on this a bit more this week and take the suggestions of what others have posted to see if it fixes it.  I am going to guess that changing the memory settings around will help, but I also need to buy more memory for my system.

[Rickinfl]

Hi,

I've been reading this forum and trying to figure out if there is a fix for this or not. I really didn't see anyone say "This is the fix" with instructions.

Can someone point me in the right direction?
Has anyone contacted the package creator?
Why hasn't anyone pulled this package from being install if there is issues with it?

They should pull this package if its not working. It pretty much killed my pfsense box and I had to remove it.

Sorry for being so direct. But I just had to shut down my firewall ports to my websites and I'm trying to get this fixed as soon as possible so I can bring them back online.

Thanks,
Rick

All the php-scripts spawned by the gui are constrained by the memory-limit set by suhosin. Which is 512MB.

That's what my perl-one-liner was for. I even increased the limit to 4GB for testing today …

[paftdunk]

@lucasrca:

How I solved my problem:…

1. Updated Firewall Maximum Table Entries: 4000000 -> 8000000

This ended up being the missing link for me. My default was 2M. When Perforado mentioned the count in  /var/db/aliastables/ I checked mine: 4.4M in those lists alone. I bumped my max table entries in System / Advanced / Firewall & NAT from 2M to 10M and pfblockerng started working again.

suhosin.request.max_value_length = 500000
suhosin.memory_limit = 536870912

Setting 'memory_limit' in the inc file is maxed by the suhosin.memory_limit.

The memory_limit is defined in /etc/inc/config.inc

// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
	ini_set("memory_limit", "512M");
} else {
	ini_set("memory_limit", "128M");
}

So for those using many IPV6 GeoIP table on amd64, they probably have to change /usr/local/etc/php.ini, /etc/rc.php_ini_setup, pfblockerng.inc as well as the Firewall Maximum Table Entries

The php memory issues are not specific to pfBlockerNG, backup crashes when backup size is too big, the Diagnostics/Tables will crash when viewing huge table, etc.

I am having similar issues + NAT / routing was not working at all.

I changed the fire wall rule # to 8000000 and added  ini_set("memory_limit", "768M");
I still see the error above. But I at lest have routing back.

Did you fix  /usr/local/etc/php.ini, /etc/rc.php_ini_setup ?
