PFBlockerNG 2.1.1_2 Memory Errors
-
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 ? -
CPU: Intel(R) Atom(TM) CPU C2558 @ 2.40GHz (2400.06-MHz K8-class CPU)
RAM: 8192MBpfSense 2.3.3.a.20160803.1621
pfBlockerNG 2.1.1_2 -
Well on amd64 the default is 512MB.
/var in Ramdisk ? getting full ?

@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. -

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:

- 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

- Load balance and failover
- QoS with Traffic shaper
- Updated Firewall Maximum Table Entries: 4000000 -> 8000000
1.1) Reboot - Edited /usr/local/pkg/pfblockerng/pfblockerng.inc and set memory limit to 500M

POST-INSTALL script failed
Message from GeoIP-1.6.9:
GeoIP does not ship with the actual data files. You must download
them yourself! Please run:/usr/local/bin/geoipupdate.sh
You will need to run php /usr/local/www/pfblockerng/pfblockerng.php dc from the shell.
Once it succeeds, you should be able to install, it may need a reboot. -
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.

What do you have for Firewall Maximum Table Entries?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.
-
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.
-
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.

Temporary Fix for
php /usr/local/www/pfblockerng/pfblockerng.php update
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
cp /usr/local/etc/php.ini /usr/local/etc/php.ini.BACKUP
perl -pi -e 's/536870912/671088640/g' /etc/rc.php_ini_setup /usr/local/etc/php.ini512 * 1024 * 1024 -> 536870912
640 * 1024 * 1024 -> 671088640 works for me. maybe your setup needs more :) -

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

What was the size of pfB_Top_v6.txt before the MaxMind db change ? I do not use these table, so I can't compare.
On option BBcan177 mentioned was that he might need to aggregate the table to shrink them.

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.
