      Thank you for this workaround!

      Disabling the CPUs seems to solve my problems for the moment.

      On my Supermicro MBD-X7SPA-HF with Quad em pcie card, using multiple vlans and ipsec tunnels:

      • Traffic on vlan Interfaces dead after some time. From 15min up to a few hours at most.
      • Wan and pfsense still responding
      • Reboot solves the problem (multiple times a day)

      Same behaviour with a replacement asrock Q1900M and Quad em card.

      Other observations:

      Old alix 2d13 runs fine with the same vlan/ipsec setup (very slow, but ok as backup).

      2 boxes with a gigabyte j1900n-d3v also run fine without disabling the cores:

      • using the onboard re interfaces
      • they also have some ipsec tunnels
      • they do not have vlan interfaces

        Only that the ifconfig down/up stuff even worked before I disabled the cores… :-)

        I now have a cronjob that checks the LAN interface every minute and if it cannot ping internal systems restarts the interface and logs it to system.log. If you need me to run additional debugs: Go ahead please! :-)

        Regards,
          JP

        hey jp, could you share the script for that cron job?
        in my case alix apu box stays up, no problems with it. sg2440 locked up once and soekris 6501 locks every couple days.

          Sure..

          
          #!/usr/local/bin/perl
          
          use Net::Ping;
          use Sys::Syslog;
          
          $server_to_ping="192.168.1.1";
          $server_to_ping2="192.168.1.2";
          
          sub check_ping_server
          {
          $host_alive=1;
          $ping=Net::Ping->new('icmp');
          if( $ping->ping($_[0]) ) { $host_alive=1;}
           else  {$host_alive=0;}
          return $host_alive;
          }
          
          if(!check_ping_server($server_to_ping) && !check_ping_server($server_to_ping2))
              {
              system("ifconfig igb2 down");
              system("sleep 2");
              system("ifconfig igb2 up");
              system("sleep 5");
              openlog("checkigb2", "ndelay", LOG_USER);
              syslog('notice', 'IP check failed, igb2 restarted');
              closelog();
              }
              else
              {
                openlog("checkigb2", "ndelay", LOG_USER);
                syslog('notice', 'IP check ok');
                closelog();
              }
          
          exit;
          
          

          Not the best piece of coding but it seems to do the trick.

          Regards,

            Hi been tracking the bug (thanks CMB!):

            https://redmine.pfsense.org/issues/6296

            A comment on the bug tracker had this link:

            https://forum.pfsense.org/index.php?topic=107471.msg602590#msg602590

            This user disabled the following in System/ Advanced / Networking:

            I had all enabled:

            Disable hardware checksum offload
            Disable hardware TCP segmentation offload
            Disable hardware large receive offload

            Can anyone else here confirm if this helps if they are experiencing the issue (I am working to get this hardware back online soon to test myself)

            Not trying to muddy any waters, but hoping for a fast resolution.

            Thanks

              I had these options disabled even before the upgrade to 2.3.
              Only disabling the CPU cores solves the issue for me.

                I'm having the same issue. Disable CPU cores, still under monitoring.
                Hopefully the fix release asap.

                Update:
                It does not work for me, the issue just happen again.

                  Add us to the list as well.

                  We have a virtual pfsense cluster on our DRC site with and ipsec tunnel to our prod site. Since the update, we've had constant crashes from the master on the DRC site.

                  It has been stable for the past 2-3 days now, but with a VCENTER session open, I see a constant CPU usage warning on the master on the other side. We have done the CPU workaround too but as soon as we launch our VEEAM replications, we can be pretty much sure that the ipsec tunnel will fall. Def looks like all the UDP traffic is basically doing a DOS…

                    We're still working on tracking this down. Have it narrowed down to something in our IPsec changes (which are just back-ports from FreeBSD -CURRENT), but that's still 80 change sets potentially related.

                        We also are having this problem with 2.3 , it happens each week.
                        We use multiple ipsec connections.
                        The pfsense is inside a vmware.
                        2Gb ram
                        4 cores

                        I think the state table size is also bigger: 82% (165500/201000)
                        When i want to open the state table it also crashes Allowed memory size of 268435456 bytes exhausted.
                        I will put more ram in the system when i have a downtime window.

                        –--
                        Yes i got my down window upgraded the ram to 4Gb, can now view the states without any problem.

                          Happened again today twice but with different details.

                          1. LAN went down. For whatever reason my script doing ifconfig down and up did not help. I tried manually with no luck. Retried and introduced longer sleep between down and up and then it worked. This was the first crash in several days.

                          2. appr. 60 minutes later LAN was down again. However this time I did not even manage to get any result on the serial console. I had to power down/up. No core dump I was able to find however after login I saw a crash and uploaded it. not sure if it is related. I would say it happened around the time of (1).

                              A other firewall of us got stuck just now, when i looked at the console it was showing a different wan adres.
                              It seems to have been reverted to a private, will take a screenshot next time.

                                We seem to have a fix for this. It's not yet merged into the source tree, but will be soon.

                                It's not universal or even close to it or we wouldn't have released with the issue. Not ISP-specific. Just happens the traffic profile of some systems will encounter it. Certain UDP streams is what triggers it.

                                      Hello,

                                      any news on this ? Is there a special setting or a patch to fix the issue available ?

                                      Thx.

                                        Reducing the system to one core is the only workaround. The fix was merged into devel branch today and hopefully into RELENG_2_3 tomorrow, in which case it'll hit snapshots tomorrow.

                                          Then I have upgraded to the new snapshot that came this morning (2.3.1-DEVELOPMENT (amd64) - built on Thu May 12 00:18:20 CDT 2016 - FreeBSD 10.3-RELEASE-p2), and will check it out.
                                          I have also removed the temp workaround, from /boot/loader.conf.local
                                          The temp workaround for me were to add these lines into loader.conf.local
                                          hint.lapic.1.disabled=1
                                          hint.lapic.2.disabled=1
                                          hint.lapic.3.disabled=1

                                          When I entered these lines pfsense were stabile for me, but now I have enabled all cpu cores again, and hopefully the new snapshot will work just fine.
                                          Before the workaround I did have 10-12 “crashes” a day.
                                          I will post back if the new snapshot works Ok or not.

                                          UPDATE! Before i managed to post this my pfsense crashed again with the new snapshot. I will try to disable all but 1 cpu core again, still using todays snapshot.

                                            There is no fix yet, as I noted. Watch the bug ticket for updates.
