      I've had an issue for a few weeks now that when I max out my outbound connection for a while (for example firing off a big photo upload from my phone) then the WAN link dies and won't reconnect. Obviously during lockdown it's become quite an issue, kicking people out of conference calls etc.

      When it happens I just get a repeated set of system log entries (below), each with a new process ID until I reboot. I don't need to reboot the bridge, just pfSense. Before I wipe & rebuild, is there anything specific I should look for?

        What snapshot are you on?

        Can you try to force a reinstall of mpd? pkg upgrade -f mpd5

          I’m on 2.5.0.a.20200502.2108.

          I’ll give that command a try and report back.

              OK, the problem may have been that the version of mpd5 you had was from a snapshot before the kernel moved to FreeBSD 12.1-STABLE. The base OS upgraded but the packages didn't get reinstalled if their version numbers didn't change. We're looking into a good solution for this already.

              In the meantime, you might want to force a reinstall of everything: pkg upgrade -f, followed by a reboot.

                Is it ok?

                  Looks like I spoke too soon. We pushed it extra-hard and it was fine yesterday but it's been flaky again today.

                  I'm just going for a complete wipe while I've got time today to do it properly.

                    It could be Realtek NIC. If it's possible, use other hardware, If not, you may need to compile realtek driver for your network card, not sure if it's still possible to with 2.5.0 but some people have compiled and using it
