      Slight update on this. After a couple months away from  using pfSense I decided to give it another try. Same hardware as before - this time the USB Interface is my "inside" NIC.

      Same behavior - ue0 starts flapping for no apparent reason, and it never recovers. I have to reboot to bring it back. I even locked the speed/duplex down on the Cisco switch that the inside USB NIC plugs into.

      Back to the Airport Extreme for me, sadly. I love the extra capabilities that pfSense brings.

        good info, i was thinking of trying it again, but I guess not.  i tried 2.0.3 when it came out had a similar issue, no issue with 2.0.2 though, been running it (2.0.2) fine for the last few months.

          I still suspect that it's something to do with the USB Ethernet driver, since the flapping problem follows it. I still think there's two problems with it not recovering correctly when it returns. The first time it lost it's (static) LAN address, re-plugging the USB ethernet adaptor restored the IP but not the other services like routing or the gui. (Had to reboot)

            im not using an usb adaptor, but have almost identical symptoms.  maybe its a freebsd driver issue rather than an issue with pfsense?  if i had a spare nic, id give it a try, but no extras lying around right now…

              I am running on 2.1RC0 Jun12 build and am also having ue0 flapping but the connection to the internet seems not to be affected.
              Running inside a virtualbox (latest 4.2.16) with lan interface bridged to the host's lan and wan using trendnet's usb adapter.

              Just updated to latest snapshot from friday and the problem is present.
              Again, strangely enough pppoe running on the same physical interface is not affected and keeps running despite this flapping.

              Current network "hardware" :
              Running 2.2RC in Virtualbox 4.2.16.

              Retired:
              ALIX2C2 , 4 gigabyte disk cf card running 2.0 (official release).

                I was experiencing dhclient deaths when pfSense booted up and the modem wasn't online: http://forum.pfsense.org/index.php/topic,64296.msg348994.html#msg348994

                This morning, running the "Sun Jul 21 21:47:35 EDT 2013" build, I tested this situation again (involuntarily again). This time, however, everything went fine. While I still got the message that dhclient died upon bootup, pfSense happily aquired a DHCP resitration when the modem became available.

                So…nice that it appears to work for me now - but can someone else check if this issue is really solved?

                  This morning, I upgraded to the Jul 26 15:34:51 EDT 2013 version. Later on, I had to cut power to modem and pfSense, and this time, pfSense again failed to get a DHCP address via WAN. Same situation as decribed earlier, modem and pfSense boot up, pfSense starts dhclient (apparently before the modem has established the physical link), dhclient dies and doesn't come up again (this time, I waited for a few minutes only, not hours).

                  Either the issue has reappeared in one of the later builds or it happens somewhat randomly…

                    Please provide the relevant sections of the system log and DHCP log. (It seems dhclient logging has recently moved from the system log to DHCP log which probably makes it a bit harder to determine the ordering of link-up/link-down, apinger, dhclient actions.)

                      Same here.

                      Used different USB LAN Adapter - latest one is from apple.

                      WAN IP is lost after minutes or days, only fixable with a reboot (at least within my knowledge).

                        I posted some log file excerpts over here: http://forum.pfsense.org/index.php/topic,64296.msg348618.html#msg348618 - probably forgot to provide that link in the here.

                        I had a scheduled power outage yesterday in the afternoon again (if you're curious: I had one or two unscheduled/unpexted power outages, and following these, I began debugging my frdige (the thermostat was broken, so I replaced it with an AVR and a 1wire temperature sensor). Unfortunately, I didn't provide an ISP connector, so I have to pwoer down the fridge to pull the microcontroller to update the firmware. Even more unfortunate, getting access to the power cable would require me to take apart about half of the kitchen - so laziness dictates that I just flip the fuse. Of course, the kitchen is on the same fuse as the living room, the terrace and my office room…).

                        Well, this time (firmware was that of the morning of July 28th), everything worked fine.

                        Okay, and here's the system log output from the WORKING bootup:

                        With this WORKING case, I can also see the dhclient restart in the DHCP log:

                        
Jul 28 20:14:47 dhclient: PREINIT

                        Well - I am not totally convinced that it depends onb the build whether this issue appears or not. At least I don't regular commits comments like "broke dhclient again after fixing it yesterday".
