      so it happened again

      arp table is empty except 10.18.66.1 which is the router and wan vips

      lan / wan interface is up

      packet capture on lan shows

      08:18:11.832770 ARP, Request who-has 10.18.66.8 tell 10.18.66.1, length 28
      08:18:12.221318 ARP, Request who-has 10.18.66.15 tell 10.18.66.1, length 28

      08:18:14.570169 ARP, Request who-has 10.18.66.10 tell 10.18.66.1, length 28
      08:18:15.113532 ARP, Request who-has 10.18.66.8 tell 10.18.66.1, length 28

      again im able to access the router through ipsec tunnel and reboot it which fixes it until the next time it happens.

      after the reboot arp is populated again and packet capture shows activity on LAN interface.

      also i believe this node was 2.2.4 to 2.3 and i didnt remove the only two packages before upgrade: pfBlockerNG and siproxd.

        it keeps happening. i do have two dhcp pools on the subnet for pc/phones with deny in mac control (partial phone mac) on the main PC pool. but that works after reboot. i turned it off for testing. i guess nuking with backup is the last resort

          That shows it's sending traffic and not receiving anything. Do you have kern.ipc.nmbclusters configured in /boot/loader.conf or loader.conf.local? If not, add this line to loader.conf.local:

          kern.ipc.nmbclusters=1000000

          and reboot. With e1000 NICs I doubt you're exhausting mbufs, but that's a potential symptom in that circumstance.

          If it happens again with that, try running (where em1 is your LAN NIC, replace accordingly):

          ifconfig em1 down
ifconfig em1 up

          and see if that does anything. That may narrow it down further.

            kern.ipc.nmbclusters=10000
            was set in loader.conf.local, i changed the value to 1000000 per your post and the system didn't come back online. no ssh/ipsec/wan response. i have to go on site and change it back to 10000.

              after setting kern.ipc.nmbclusters=1000000 system never booted up it was hanging at
              run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_action

              i tried to set the variable back to 10000 preboot and it was still doing the same. decided to intall 2.3.0 fresh and restore the config. so far so good. i'll repost if the issue continues.

                fresh install of 2.3 and restore the config with only pfblocker and siprox still does the same thing. LAN loses internet and reboot helps until the next time it happens. i'm going to switch back to 2.2.4 which was the rev i started this upgrade with.

                    Oh, and ifconfig em1 down and then up does help!

                    If you need anything else (tcpdumps, other stuff, etc..) let me know.

                      Hi all, back with another update after a BIOS upgrade and a complete fresh install, but the problem remains.

                      I didn't see it yesterday but there are errors in the dhcp log:

                      Apr 22 08:53:50	dhcpd		dhcp.c:3763: Failed to send 300 byte long packet over em1 interface.
Apr 22 08:53:50	dhcpd		send_packet: No buffer space available
Apr 22 08:53:50	dhcpd		DHCPOFFER on 192.168.10.100 to 00:b5:6d:00:d8:09 (R9Z0F0V) via em1
Apr 22 08:53:50	dhcpd		DHCPDISCOVER from 00:b5:6d:00:d8:09 (R9Z0F0V) via em1

                      That does not seem good! Any suggestions on this?

                      Regards.

                        Could you download the status tgz file from status.php and get it to me? Email cmb at pfsense dot org or PM me here to arrange transfer.

                            I too am having this same issue on every box I have upgraded to 2.3.  I have to say I have been pulling my hair out thinking I was the only one till I came across this thread.  I am using several different platforms but for the sake of uniformity and just trying to get to the heart of the problem, let's cover the machines I am using most.

                            Firebox X750e and Firebox X1250e
                            2gb RAM
                            4GB CF
                            pfSense 2.3 nano embedded
                            LAN plugged into port 1 (sk0) of internal 4 ports
                            WAN plugged into port 1 (msk0) of 4 port expansion card
                            Firmware is upgraded and patched for serial port console during/after boot.

                            Symptom:  The LAN connection goes out to lunch arbitrarily.  I can unplug the cable and plug it back in and the LAN port is active again.  Ultimately, it will go out to lunch again.  The connection and activity lights will go out typically when this is happening but not all the time.  When plugging the cable back in the lights come back every time if they were off.

                            I figured it was an issue with plugins however I have reluctantly uninstalled all plugins however the issue persists.

                            We were experiencing this issue with the WAN port as well but we did the disable of the hw.msk.msi_disable=1 and the WAN ports have not dropped out since.  Granted, it's just been a few days so far… knock on wood.

                            I am going to move the LAN port over to an extra expansion port and see if there is a difference there.  Will report back.

                            Let me know if there is any additional information that may assist in this troubleshooting process.

                            Thanks

                              we switched back to 2.2.x but it seems that

                              https://forum.pfsense.org/index.php?topic=110710.30

                              could be also a reason but i haven't' tried the workaround which is to only run it on 1 core. i'll wait for out of the box solution since these are production systems.

                              Thanks

                                So after moving the LAN port over to the expansion card of the firebox we have not had a drop out on the LAN yet.  In addition, since doing the hw.msk.msi_disable=1 the WAN port still has not dropped out.  Any reason we should suspect the on board 4 port ethernet interface drivers as the culprit here?

                                I'm also going to upgrade an existing vmware ESXi 5.1 box where I have pfsense running as a virtual firewall and see what happens there.
