        That's generally a symptom, not a cause. What's going on with the system at the time? System log.

            Yeah with the link cycling non-stop, check_reload_status will be at high CPU usage, it has to do a number of things any time a link goes up or down and you're doing all those in a non-stop loop there. Question is why was the link flapping. Most likely causes given a reboot fixes, either the NIC is flaking out, or the device it's plugged into is flaking out. Most likely not cabling-related if a reboot fixes. The reboot in and of itself is unlikely to be the fix, it's most likely the fact that the link went down for a significant period of time during the reboot and was brought back up. If it happens again, work to eliminate one of those two causes.

              Meeeh it was update.
              I upgraded to latest snap 5 days ago and now it runs just fine for 5 straight days…
              NIC 100% OK, cable too. So it was snap issue afterall...

                Hi again!

                I found a way how te replicate this….
                On my pfsense, there are 4 identical NICs.
                One of them fxp2 is causing problem but only when I reboot server to which it is plugged in.
                Any idea why link is not established back?

                  Huh thats odd…
                  LAGG interface comes up just fine.
                  other interface used for pppoe aswell...
                  Just this NIC seems to cause problems...
                  Maybe driver update?
