      No I am not having squid listen to anything but the 3 different vr networks.  I am just wondering if the setup may have something to do with it.  Doesn't hurt to recreate it completely.

          @LostInIgnorance:

          EDIT: Did you try it with squid havp, etc. loaded on it?

          I haven't tried it with squid, I'll load that on next. Do you have the OpenVPN server assigned as an interface and squid listening there? Otherwise, squid wouldn't be doing anything to the traffic coming from OpenVPN

          Jimp,
          it was most likely missed in this thread, but in my original thread with this problem from 12/13
          had the packages i am running.  http://forum.pfsense.org/index.php/topic,31031.msg165512.html#msg165512

          Packages i am running:
          Squid
          Squid Guard
          Snort
          OpenVPN Export
          Light Squid
          Anyterm

          If need be, i can test by stopping Squid and such….

            It might be worth trying without any packages. (the only one I have is OpenVPN client export) to see if it makes a difference.

            One thing - for everyone seeing the panic on em(4) devices, the output from

            pciconf -lvb
            

            For the em card seen in the crash would be helpful.

              ??? JimP, I am a little confused, do you want me to type that in after the crash happens and the db comes up? If not, what would you like from the crash?

                I have a net5501-70, a Pro 1000GT (pci), and a spare pppoe DSL line. Jim, I can set this up with openvpn if you want to test against it. I have no experience with openvpn though, so would need some guidance setting that up.

                Also note that my DSL line has pretty poor sync rates right now, and occasional disconnects, which is why it's not in use :/

                db

                  Just at a normal command prompt. It will show the chip id of the em card.

                    I'll keep that in mind, though I was hoping to do it locally since that makes it a lot easier to track down…

                          Chip ID is the same on both of those, and on another one I'm talking to that crashes… Mine that run fine are a different chip.

                            Interesting, my SM board has the same chip ID. My panics come around at 6-8 day intervals with no vpn use, no known factor other than time elapsed.

                              LostInIgnorance - one more test for you since you seem to hit it faster than anyone else - can you try switching your OpenVPN instance to TCP instead of UDP and see if it makes any difference? Just curious.

                                Just another "me too" .. panics in devd on the carp backup host.  Just got them while adding firewall aliases on the primary (no recent changes to VIP addrs).  I'll report if tomorrow's snapshot doesn't stop them.

                                  vito and others with em failing, can you look at the output of this:

                                  sysctl -a | grep 'dev.em.*fail'
                                  

                                  And report any non-zero values. Specifically with dev.em.0.mbuf_alloc_fail and dev.em.0.tx_dma_fail

                                          Can anyone of you please test with this kernel http://files.pfsense.org/kernel.gz
                                          Just copy it under /boot/kernel/kernel.gz on pfsense and reboot.

                                            For those wanting to debug on ALIX/other embedded devices…

                                            /etc/rc.conf_mount_rw
                                            fetch http://pingle.org/files/kernel_wrap_Dev.gz
                                            tar xzpf kernel_wrap_Dev.gz -C /boot/
                                            
                                            

                                            And then reboot. It works on my ALIX.

                                            The next snapshot after the one building now should have them in there as well, but not the one building now.

                                            Should I use the above process, just changing the file to http://files.pfsense.org/kernel.gz?
