PFBlockerNG 2.1.1_2 Memory Errors
-
How I solved my problem:…
- 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.

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 …
For those wandering about suhosin, it is defined in /usr/local/etc/php.ini
; File generated from /etc/rc.php_ini_setup output_buffering = "0" expose_php = Off implicit_flush = true magic_quotes_gpc = Off max_execution_time = 900 request_terminate_timeout = 900 max_input_time = 1800 max_input_vars = 5000 register_argc_argv = On register_long_arrays = Off variables_order = "GPCS" file_uploads = On upload_tmp_dir = /tmp upload_max_filesize = 200M post_max_size = 200M html_errors = Off zlib.output_compression = Off zlib.output_compression_level = 1 include_path = ".:/etc/inc:/usr/local/www:/usr/local/captiveportal:/usr/local/pkg:/usr/local/www/classes:/usr/local/www/classes/Form" display_startup_errors=on display_errors=on log_errors=on error_log=/tmp/PHP_errors.log extension_dir=/usr/local/lib/php/20131226/ date.timezone="America/New_York" session.hash_bits_per_character = 5 session.hash_function = 1 ; Extensions ; opcache Settings opcache.enabled="1" opcache.enable_cli="0" opcache.memory_consumption="50" [suhosin] suhosin.get.max_array_index_length = 256 suhosin.get.max_vars = 5000 suhosin.get.max_value_length = 500000 suhosin.post.max_array_index_length = 256 suhosin.post.max_vars = 5000 suhosin.post.max_value_length = 500000 suhosin.request.max_array_index_length = 256 suhosin.request.max_vars = 5000 suhosin.request.max_value_length = 500000 suhosin.memory_limit = 536870912Setting '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.

Hello!
I also had this problem. Editing the files as described earlier (including The memory_limit defined in /etc/inc/config.inc where I increased the amd64 limit to 640M) was part of the solution for me.
The last thing for me was to increase the Firewall Maximum Table Entries: 2000000 -> 10000000. When using pfBlockerNG the total of firewall rules are about 4500000 rows now. Reloading those rules requires about 9000000 table entries since that the new rules are loaded before the old ones are deleted ending up with temporary 9000000 million rows in the table.
If you have lesser than 9000000 you will get an out-of-memory error message plus that some rules are not loaded correctly. -

I've submitted a PR to pfSense's GitHub repo:
https://github.com/pfsense/pfsense/pull/3101After that, the following changes suggested by @Perforado on the package could be implemented and should work.

I don't think you need that PR, if you are following the pfBlockerNG v2.0 w/DNSBL thread, you should have known that we are working on a fix that shouldn't require modifying memory_limit or php.ini.

I don't think you need that PR, if you are following the pfBlockerNG v2.0 w/DNSBL thread, you should have known that we are working on a fix that shouldn't require modifying memory_limit or php.ini.
A 55 page, nine month old thread introducing the feature seems like a weird place to have active commentary on fixing the bug reported in this one.
-
This thread is about fixing memory issues introduced by MaxMind database changes.
The post about "Blocking the world" is about people configuration that trigger the bug.
It is normally useless to Block the world and the comment is in the right place in the pfBlockerNG w/DNSBL thread.The thread has 55 pages, because pfBlockerNG is not trivial to configure.
Since when the size of a thread make it irrelevant to read it? -
Following the following instructions I have trashed my pfSense install and receive the following stack trace on boot:

I followed the post below, and then ran the geoip download which completed successfully. Then while running the update from pfBlocker it froze, and the network went down. Now the DHCP does not assign addresses to the network and I cannot access the box except going directly to it with KBB and monitor.
Reverting changes and rebooting does not resolve. Running any option from the terminal returns the above error. If only the devs hadn't removed the script for manual backups and recovery….

So what modification did you do.
On i386, only the pfblockerng.inc fix is normally required.The config.inc was just stated for referenced.If you modified it, maybe you forgot to put the "M" in 256M? (262144 bytes exhausted)The /etc/rc.php_ini_setup & /usr/local/etc/php.ini fix is for amd64 that need more than 512MB.
-
Thanks Ron…a little M goes a long way to making the system work. 2048 instead of 2048M.

Thanks Ron…a little M goes a long way to making the system work. 2048 instead of 2048M.
And where did you made the modifications ? 2048M in config.inc might break something else somewhere.
-
// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "512M");
} else {
ini_set("memory_limit", "128M");
}changed to
// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "2048M");
} else {
ini_set("memory_limit", "128M");
}reverting to default shouldn't hurt as pfBlocker is uninstalled until a real fix is in place.
-
I would put it back to 512MB.
Modify the pfblockerng.inc instead, this will only affect the pfblocker pkg.
However, the php.ini limit is 512M, so if you need more than 512M, you will need both fixes, the one for php and the on for pfblockerng.inc. -
Will do, thanks.
