      The watchdog that is from the em driver is a software watchdog, not a hardware watchdog and has nothing to do with the BIOS.  The code has a timer that runs, and periodically checks the status of the hardware.  The error message means the software thinks the transmit side is stuck;  outgoing packets are queued up,  but the queue is not getting processed, so it backed up.  One side of the queue is the software sending a packet, the kernel checks to see if there is room on the queue, puts the packet on the queue if there is or drops it if there is not.  The other side of the queue is the NIC hardware:  that pulls items off the queue and puts them on the wire.  After a packet is on the wire the hardware typically generates an interrupt, the driver code marks that place in the queue as freed and life is good.  If the hardware does not pull packets off the queue, the queue will back up and the transmit side grinds to a halt.  A typical reason that the hardware won't pull packets from the queue is because it thinks the link is down.  Lots of stuff happens automatically in the hardware for you, at the phy level on a NIC.

      That is what we have happening;  that is the reason why the driver is doing the "watchdog timeout – resetting" to clear the hardware.

      Now this may be a false failure:  something else could be happening that is preventing the hardware from generating the interrupt or the driver code from processing it.

      Adding a switch on either or both sides:  it gives a data point.  The pfSense interface plugged into a switch instead of where it is now should give you confidence that the link is not physcially bouncing on you.  Think of a typical configuration:  cable modem to WAN of the pfSense box, pfSense LAN to a swtich or wireless router.  If the ISP does something that causes your cable modem to bounce the WAN link, you won't realize it, but the pfSense box will see it.

      Again, since I don't know your configuration or the hardware either side of the pfSense box is hooked to, I'm trying to make educated guesses, based on what I've done/seen in the past.  It's possible that something changed in the driver between 2.2.6 and 2.3 (2.2.6 is FreeBSD 10.1, 2.3 is FBSD 10.3) that is triggering this, but I don't know.

      If you can, get the output of
      ifconfig -a

      Some of the things you can find by googling "freebsd em driver watchdog timeout" talk about disabling things like TSO.  ifconfig will let us know what options are available/enabled on your hardware, then it's just figuring out how to turn them off in pfSense (probably on the interface configuration page).  TSO is a likely candidate for causing problems.

        @mer:

        Yes, Frank's confusing this with something completely different and entirely unrelated.

        This is an apparent em driver regression between FreeBSD 10.1 and 10.3. Or maybe an OS-level change related to it. One thing I'm curious about is whether having netmap enabled is the source of an edge case issue with some em cards. That's maybe the most significant difference in our kernel and stock FreeBSD 10.3 in that regard, so it's worth a shot. I compiled a kernel minus netmap. Not something I want to publicly link at this point, but SoloIT I PMed you a link and instructions if you can please try that.

            FYI, I have another piece of hardware that was suffering the problem much worse using igb interface.

              I'd take cmb up on the offer of the kernel he built without the NETMAP option;  it should have removed the NETMAP option completely from the kernel.  The em and igb drivers should be from the same code base so it is possible they share a problem.

                Firewall box with em NIC and modified kernel is up and running. It's seems to be routing traffic as normal. I should know by morning how it's holding up. In the past it has crashed during my remote back which moves a lot of data.

                I will keep everyone posted. Again thank you all for your help.

                  13.5 hours and no crashes. I did have odd stuff in my system.log. Any ideas?

                    Well, that's good news on the modified kernel.  Are 10.10.1.1 and 10.10.1.177 IPs in your network?  If you ssh/console to the box, ls /usr/local/www are any of those files/directories present?  Should they be?

                      10.10.1.177 seems to be infected with some Malware i guess  :o

                        10.10.1.1 is the firewall and 10.10.1.177 is client. I'm so tired of looking at the log files, I total glossed over the accessing IP. I'll look into it and see if there is any malware on the machine.

                        I did not look for all the files/folders, but the dozen or so I checked do not exist.

                        Thanks for the second set of eyes.

                          That 10.10.1.177 indeed looks to be compromised, or possibly running a vulnerability assessment tool but that list seems to match known malware. Something on that machine is scanning looking for common vulnerable pages.

                            Thanks I am looking into that client. It's used by a part time person, so it explains why I've not seen it before.

                            Good news, the patch is still holding up. No crashes. I'm planning to roll the patch to the other firewalls tonight.

                            This weekend I'll also change back to my other hardware platform for the one odd location using the igb NIC rather than then em that most of my firewalls use.

                              I did update all my other firewall's with the patch yesterday evening.
                              This morning, the first test box I had installed the patch on encountered the same watchdog error:

                              Above is the system.log from when it started. There is nothing before. Once it starts, this set of error messages just keeps repeating until I reset the firewall. Since it was the LAN port acting up, I could still ping the firewall from the WAN and establish an OpenVPN connection. Also, my IPSec tunnels remained running.

                              I was really hoping the patch fixed it the problem as it was running for over a day and typically locked up before then. Suggestions are appreciated.

                                Anything happening at about that timeframe, backups, remote transfer of lots of data?  One of the other users of the modified kernel reported a problem after awhile, during a transfer of large amount of data.

                                In all the other cases of you having an issue, was the WAN side still alive but the LAN side dead//stuck

                                  Yes, a lot of data was being moved as a back to a remote site was in progress.

                                  In the other cases, the port that locks up is random. I've had both LAN and WAN lock up. I don't see any pattern to which port locks.

                                    It may be a good datapoint for cmb,  I'd suggest maybe getting the status and emailing it or a link as he asked another to do here.  That'll give 2 datapoints.

                                        We've locked up 2 more times this morning under fairly heavy IPSec VPN load.

                                            Well, it could be related, or maybe not.  What that error message is saying is something is trying to create a connection, but the application handling those connections is backed up.  It could be new connections are coming in faster than the app can handle or the app is not processing the connection (maybe something else running).

                                            Links to a couple of old threads that have good info:
