            Great, you can pull the status_output file from the GUI. See:
            https://docs.netgate.com/pfsense/en/latest/recipes/diagnostic-data.html#view-and-download-diagnostic-data-in-the-gui

            Then upload it here:

                  Mmm, OK nothing obvious there. I'm going to consult developers on this.

                    Ok, the likely cause here is a race condition between filter reloads triggered close to simultaneously.

                    That obviously shouldn't happen but you can probably mitigate it by tuning your gateway parameters for the WG_VPN_HQ gateway. Currently that is continually throwing alarms and reloading the filter every time it does. I suspect when you see this error it ends up thowing several alarms and queing up reloads.

                    I would try either setting the monitoring values to far higher numbers, say 50% and 500ms, or disabling monitoring action on the gateway. If that prevents or reduces the errors you're seeing that would prove the theory.

                    Steve

                      @stephenw10 From a troubleshooting standpoint, it makes sense since these overseas vpn can have spotty connection from time to time. I already made those adjustments... waiting to see what happened :D Thanks @stephenw10 much appreciated!

                        I’m also seeing this message pop up a lot recently on one of my 23.09.1 firewalls. I’m counting 8 messages between 4/15 to today (4/28).

                        It’s always an alert saying:

                        There were error(s) loading the rules: pfctl: DIOCADDRULENV: Device busy - The line in question reads [0]:
                        

                        Followed by another alert saying:

                        PF was wedged/busy and has been reset.

                          Same question as the OP here. Anything logged? Any 'exotic' rules? Anything else unusual?

                              Is there anything else logged? An alert shown in the system?

                              Can you replicate it by running Status > Filter Reload?

                                        Hmm, nothing obviously an issue there.

                                        You have a lot of bad requests against the pfSense GUI from a single IP. If that's not a scan of some sort from an internal IP you should check that you don't have open ports to the WAN.

                                        One in stance showed just after em2 disconnected. But only one.

                                        It looks like you have lcdproc installed but misconfigured.

                                          bad requests against the pfSense GUI from a single IP?
                                          Can you tell me which IP? or which log file?

                                          It looks like you have lcdproc installed but misconfigured.
                                          I'm running lcdproc on a watchguard xtm550, the lcd is showing the correct info?

                                            An XTM5 you mean? In that case lcdproc is probably just trying to start multiple times:

                                            I see you upgraded the CPU. 👍

                                            You have a bunch of arp movement logs:

                                            arp: 192.168.2.187 moved from 52:04:aa:49:5d:ce to da:53:be:3f:8b:a7 on em1
                                            arp: 192.168.2.187 moved from da:53:be:3f:8b:a7 to 52:04:aa:49:5d:ce on em1
                                            arp: 192.168.2.187 moved from 52:04:aa:49:5d:ce to da:53:be:3f:8b:a7 on em1
                                            arp: 192.168.2.187 moved from da:53:be:3f:8b:a7 to 52:04:aa:49:5d:ce on em1
                                            

                                            If that's something known to share a MACs (internal teamed NICs etc) consider suppressing that logging as it's hiding other stuff:

                                            The logs showing the potential scan attempts are in the main system log like:

                                            That is an external device at 78.153.140.151 sending requests that are hitting the pfSense webgui. It's looking for files that might be present in known vulnerabilities. They aren't on pfSense so it throws an error but that traffic should never be allowed to reach the webui.

                                            It looks like you have some floating rules in place that pass all traffic that is not subsequently blocked but you don't have any block rules so everything is passed!

                                            anchor "userrules/*"
                                            pass inet from any to any ridentifier 1609758534 keep state label "USER_RULE" label "id:1609758534"
                                            pass inet6 from any to any ridentifier 1609758534 keep state label "USER_RULE" label "id:1609758534"
                                            

                                            You almost certainly don't want that! Disable or remove that rule.

                                            None of that would cause that pfctl error though.
