      Out of curiosity, what type of network cards do you have in that box? Is it rl and em both? Or just em? or just rl? Or something else?

        one em network (gig embedded on the board of an old dell p4).  All network traffic is VLAN'd on that one interface.

          OK, just checking… It looks odd to me that the backtrace references ed_probe_RTL80x9 which is a really old realtek chip, but it may just be something weird that I don't know at that level in the kernel/network stack.

          We have arranged serial console access with someone who has been able to reproduce the panic so hopefully we'll have a lead on a fix early next week.

            Here's an extract from the stack trace:

            m_freem(c2feeb00,4,c0e6e75d,b87,c2f4e000,...) at m_freem+0x43
ed_probe_RTL80x9(c2f52580,0,c0e6e75d,546,c2f525bc,...) at 0xc06ec4d8
ed_probe_RTL80x9(c2f4e000,1,c0eb8bcc,4f,c2edb918,...) at 0xc06efea0
taskqueue_run(c2edb900,c2edb918,c0ea5f85,0,c0eb222b,...) at taskqueue_run+0x103

            Note the two ed_probe_RTL80x9 references are not accompanied by a symbol name and offset. I suspect ed_probe_RTL80x9 is merely the closest lower value global symbol but its too far away to warrant printing the PC as symbol+offset. If that is the case you shouldn't take too much notice of the ed_probe_RTL80x9.

              JimP, is there anything I can do to help out?

                Not that I'm aware of. If the mbuf tag patch isn't the cause, it almost has to be the recent e1000 driver update (em, igb, etc).

                  Someone else had seen that once but so far we've been unable to replicate it so the real cause can be tracked down.

                  It seemed to be something in the configuration, though.

                    I am afraid to update since I haven't heard anything back.  Is it still crashing or has it been fixed?

                      Nothing has changed with the drivers, but there are plenty of other things that have been fixed, it may be worth trying.

                        How can I get the logs (system.log is flushed every boot ?) so I can help targeting the problem ?

                        I have 4 NICs (5 if), all Intel em, both PCI NIC or MB integrated NIC.
                        The computer just freezes, no reboot.

                        I have nmap and bandwithd installed. I'm using outboud Multi Wan, DHCP server, no VLAN, no traffic shaper, no VPN.

                        All was running good with an old snapshot. Freezes started after an upgrade a week ago. I currently have the lastest snapshot installed.
                        The freezes are random, sometimes pfSense runs some minutes, sometimes some hours.

                        Any FTP transfert aborts with an error (There were problems a week or so with passive FTP, but they were connection problems, here transferts are aborted).
                        I think this can be linked to the problem if a buffer in the driver is the problem.

                          If you are seeing a freeze and not a reset/panic, then this thread isn't related. Start a new thread for that. These drivers haven't changed for several weeks now.

                            built on Wed Jan 12 18:01:47 EST 2011

                            I just experienced my first kernel panic last night after more than 8 days uptime. I'm using a SM X7SPA-H board with only the onboard Intel GBE (Intel 82574L Gigabit Ethernet). I'm not using openvpn, but both NICs have multiple vlans on them and deal only in tagged traffic.

                            Is there a reasonable chance that updating to the latest snap will resolve this? I don't know that I can reproduce this panic intentionally, as it hasn't happened before and I wasn't doing anything interesting when it happened. I do have clients, but the panic happened at my lowest traffic period of the day.

                              I don't think we have done anything that would have fixed these panics, if it is driver-related.

                              Are you able to switch to a developer kernel so you can obtain a backtrace?

                                JimP,
                                I will be trying the old dell with the gigE port today to find out if any changes you mentioned above may have done something.  I haven't had the downtime lately to put it back into the system.  Took that computer out and used another with 2 100 nics and got it running so I could remote back into the system.
                                So it wouldn't be worthwhile to put that old dell back in?

                                  I'll see about a backtrace. Shouldn't be a problem.

                                    It may be worth trying again on a current snap. At least on today's snapshot FTP no longer freezes my router :-)

                                      Hi,
                                      I think that I'm experiencing the same problem here: I have 2 boxes running latest beta (2.0-BETA5 (amd64) built on Fri Jan 21 00:30:42 EST 2011 ) of pfsense (I have another cluster of pfsense 1.2.3 running) that I'd like to move to production soon (tomorrow or the day after tomorrow  actually :-D): I have the sync enabled, and when I add another CARP IP on the primary box, the secondary crashes (I was able to reproduce it 4 times, the last one with a devel kernel).
                                      This happens as soon as I create the new vip on the primary (the sync starts), not after pressing apply.

                                      You can see a picture of the crash + backtrace.

                                      An interesting thing: the third time I tried (the first one with the devel kernel) I was able to create the carp ip on the primary, and it was successfully synced on the secondary.
                                      But on the secondary logs I can see something that to me it looks like a "soft" or "recoverable" panic.

                                      What do you think?

                                      thanks

                                          Thanks for you prompt support.
                                          I've upgraded to 21 Jan 23:51 but the secondary still crashes, do you need a backtrace? Or is this snapshot not new enough?
                                          thanks

                                            I am still getting the panic on my home Soekris net5501-70 board when using openVPN.  I am unable to load the developer kernel on here since the board is an embedded system without a display.  The board refuses to boot once loaded with the developer.  Is there another way to grab the panic?  I am using a HD in place of a cf card since I am running squid and HAVP.
