      Hello everyone
      i run pfsense 2.0.3 on ibm x336 - 2X dual core / 4GB ram / 2x136GB iscsi (raid1 hardware)
      i have 2 of those working in master and backup in carp
      before adding the carp and also after -
      at specific times of day pfsense stops forwarding traffic to and from the servers behind it
      (i use many public ips as i host many websites and vps's) and everything just stops
      i can log in to pfsense from inside or outside the network with no issues, it seems all public ips stop responding (i work with nat, not transparent firewall), i can resolve this by restarting the lan (ifconfig bge0 down - ifconfig bge0 up) but it fails again a few times before staying on for about 20 hours, and then again, this has been going on for a while now - cold/hard reset doesn't solve this also
      packages i use: snort, pfblocker

      things from logs:
      Error while feeding rrdtool: Broken pipe
      /usr/local/bin/rrdtool respawning too fast, waiting 300s

      nothing else
      appreciate any help

          That logged error is normal and nothing to worry about.

          Since you're using Broadcom NICs you should probably try this first:

              :-[ - the solution above seemed to have improve the situtation by far
              however this morning it happened again, all nat was dropped until i restarted bge0

              anyone else has seen this?

              any help would be appreciated

                now its even worse
                it works for less than a minute after bge0 restart and falls back again

                    Hmm, interesting. What changes did you make exactly that initially seemed to help?

                      Hey Steve
                      i have added the lines exactly as they are shown on the tutorial you directed me to
                      it seemed to last for 48 hours before failing again

                      so i have added the intel nic boot loader settings as well, (i have previously added an intel network card with 2 nic)
                      and i have changed this:
                      WAN BGE1
                      SYNC EM1
                      LAN BGE0

                      to this:
                      WAN BGE1
                      SYNC EM1
                      LAN EM0

                      so far so good (been a few days)

                      thanks a lot for the help!! i hope i have seen the pfsense fail for the last time  :)

                        Good to hear.  :)
                        I only asked because other users have reportedly done that and ended up misinterpreting the instructions etc.
