      Unlikely to be a significnat power draw difference between 2.5.2 and 2.6/2.7.2 IMO. But that is pretty small for a device with 6 NICs.

      Try running a packet capture on that NIC and see if it's still seeing any packets incoming after it stops responding.

      I assume the console still responds after that?

      Other NICs still work?

            And it's only the NIC you're trying to connect to that appears to stop passing traffic? I.e. a NIC/driver issue or soemthing in the network stack.

              @stephenw10 with tcpdump I noted that NIC stop receiving traffic.
              It happens on every NIC

                Ah so it appears to lock up the NIC/driver somehow.

                Do you mean it causes all NICs to stop passing traffic at the same time?

                Or just that any NIC you connect to will fail the same way?

                    OK so:

                    It stops responding at all on all NICs. Even to ping.

                    The console remains responsive.

                    Can you ping out from the console? To something via the WAN perhaps?

                    And nothing is logged when that happens?

                    I really expect to see some error.

                      @stephenw10 Yes
                      At first NIC responds to ping
                      If i enter 192.168.1.1 in browser and i press enter it stops working an all NICs even PING
                      Device is able to ping itself
                      So appliance is able to ping 192.168.1.1. It responds
                      Console remain responsive
                      Nothing is logged, but maybe i do not able to find some log.
                      In shell i can not see anything.

                      I tried to replace RAM and PSU but the issue persists

                        Literally nothing is logged or just nothing that appears related?

                        Does dmesg return anything different?

                        You could also check the mac stats for the NIC using: sysctl dev.igb.1
                        See if anything there is throwing a load of errors.

                            For SSH to work, you need a working interface first.
                            Console access is your friend.
                            If you know you're way around, go look here : /var/log/
                            You'll find all the logs files there.
                            Check what's been log lines were added to the most recent updated files.

                              What kinds of logs should I check?
                              How can i display log from the most recent updated?

                                  Errors in the sysctls might look like:

                                  dev.igb.0.rx_overruns: 0

                                  dev.igb.0.mac_stats.collision_count: 0
                                  
                                  

                                  Anything bigger than 0 there could be a clue.

                                  Also interesting would be if the stats stop increasing at all when the NIC stop responding.

                                      obviously if i downgrade to 2.5.2 everythings return working again.
                                      I also tried installing different filesystem ufs and zfs but issue persists

                                        What's the actual log entry there? And any surrounding it from the same time period?

                                          The dmesg.boot file might also contain important info.
