      It is pfsense plus 24.03.
      After force restarting, everything is back to normal.
      I did not see the address family error in the system logs.
      Even if my WAN pppoe went down, it should not take my whole network with it.

      And the pfsense console was unresponsive so I believe something crashed.

        I agree it should not. Something should have been logged though. Unless the logging process itself stopped.

              However, I don't know if it might be related or not but I had graylog setup on another machine with pfsense sending the logs to it. And my graylog instance was offline for a longtime. The only syslog error that I could think of was this. I may be thinking too much but maybe due to these frequent errors pfsense ran out of memory?

                Unlikely it ran out of memory, I'd expect to see a bunch of logs entries complaining about it. But you can check the historical RAM usage in Status > Monitoring.

                It looks like you have something set to use IPv6 in that OpenVPN setup and there is no IPv6 on it. Dual gateways on an assigned interface perhaps?

                'Address family for hostname not supported' means something is trying to use a hostname that resolves to only IPv4 (or only IPv6) in a place that requires the other address type.

                For example an alias with a hostname in it that resolves as IPv4 only used in an IPv6 firewall rule.

                I would expect that to be logged when the filter reloads though. Try going to Status > Filter Reload manually and make sure it loads cleanly.

                  Very weird,
                  Openvpn server is set to ipv4 only and there are only three gateways.
                  ipv6 is totally disabled on the firewall.

                  memory also looks okay

                    I this setting in the OpenVPN settings:

                    Try setting that to IPv4 only if you don;t have an IPv6 address there and then re-check the logs when it connects.

                        Hmm, maybe you have static routes to an alias via the tunnel gateway?

                          @stephenw10 nope, there is no static routes defined.
