      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.

            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

              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. :(

                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.

                  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:

                  [2.3.2-RELEASE][root@router.xxxxx.xxx]/root: php /usr/local/www/pfblockerng/pfblockerng.php dc

                  The prompt is gone it seems its waiting for something.

                      Yes it takes 5+minutes to complete

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

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

                                    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.

                                      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.

                                          • 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.

                                          This a UNIX country. On a quiet night, you can hear Windows rebooting.
