      I'm running pfSense Plus 23.05.1 without any issues. Since 3 days I'm testing a 5G failover connection. I'm tunneling this via VLAN and setup a new VLAN interface for that WAN. It's running flawless until the connection goes down and up again. After that the process "/usr/local/sbin/check_reload_status" is consuming 100% CPU all the time until next reboot.

      Don't know how to sort this issue out.

        You can just kill the process as a one time fix:

        kill 441

        If it happens again though it requires more investigation.

          @stephenw10 Restarting php-fpm also "fixes" this. But after the 5G goes down again the issue reappears.

            Every time?

            How are the interfaces configured/connected?

              Hello!

              Around 30% of my routers running 23.05.1 had check_reload_status stuck at 100%. This was not a huge problem for the faster boxes, but the slower ones (sg-3100) were inaccessible from the gui (gateway timeout). Could not kill the check_reload_status process. They needed a reboot from the shell.

              I have no idea how they got in this state. Some are multi-wan. DHCP and static IP WANs. All of them have the wan occasionally go down and come back. Pretty basic setups. Nothing odd.

              check_reload_status seems to have a history...

                @stephenw10 Not every time. But every 2-3th time. WAN1 and WAN2 are connected physically via PPPoE and WAN3 (the 5G test WAN) is connected via VLAN and DHCP. I will try to use another physical port for that interface to see if this issue still exists. But I think the gateway handling with 23.05.1 is the problem. Since that release I also do have the issue that the gateway for my Wireguard connection is disabled after bootup.

                  A regression since 23.05?

                  There is history with check_reload_status, yes, but no recent bugs for it.

                    I think it is, but unfortunately I can't diagnose it further.
                    I sold a SG-3100 to a friend that lives in another state, and he is facing the same problem.
                    PPPoE also..

                      And he definitely wasn't seeing it in 23.05?

                        Unfortunately I'm not sure.. He is not the type of the guy that monitors CPU usage and other metrics.
                        He called me to help him in something I found that problem and he was already running 23.05.1

                        All I can say is that he is using 23.05.1, multi WAN configuration, one link is PPPoE and the other is not.

                          Mmm, hard to see what might have caused that between 23.05 and 23.05.1. Far more likely to have been introduced since 23.01. Though still nothing obviously that might have caused it. šŸ¤”

                            It happened three times already, sorry I can't help further..
                            I asked him to buy a modem and let the modem handle the PPPoE for the time being, he will use the DMZ in the modem..
                            He is not using uPNP, IPv6 track interface, Voip or anything like that, so I think the DMZ option will work fine for him..

                            If there is something that I can check during the next event, just tell me and I'll check with him next time.

                              Hello!

                              I traced the point of failure on two routers back to 8/3 using Status -> Monitoring.

                              They are both in the same comcast service area that was having persistent outages for about 2 hours - WANs going up and down.

                              One router is single wan dhcp. The other is dual wan comcast static ip and dsl pppoe.

                              The single wan is a sg-3100 and the dual wan is a fw4b. Both on 23.05.1

                              Both routers seemed to be running fine for almost 30days with check_reload_status stuck at 100%. I only noticed it on the 3100 when I tried to login.

                              Even though check_reload_status was at 100%, the system load was significantly lower. System/nice util at 13% on the fw4b and system 35% / nice 15% on the 3100.

                              I probably never would have noticed it if I didnt need to login to the 3100.

                              What (other) problems can check_reload_status cause when it is stuck?

                              John

                                Well it uses CPU cycles so you would see reduced throughput etc if you were already close to the hardware limits.

                                Let me see what I can fins here.

                                  @stephenw10 Right now it happened again. I figured out that after reconnecting the 5G modem the WebGUI gets very unresponsive for couple of minutes. Also another gateway (CYBERGHOST) is losing it's connection (seems to be restarted). Took 5 minutes until the 5G got it's public IPv4 via passthrough mode. After that check_reload_status is at 100% again.

                                  This is the log while that happened:

                                    Hmm, it actually took 5mins? Because the 5G router didn't have an IP for that long?

                                    That is at least unusual. Obviously that shouldn't make any difference but....

                                      @stephenw10 5G modem took around 1 minute to bootup and getting an IP address.

                                        And pfSense took a further 4 mins to pull a dhcp lease?

                                        What was logged in that time? In the dhcp and/or system log?

                                          @stephenw10 Unfortunately did not check that. I did now use a physical port for that connection and will see if the error still appears. Otherwise it's an issue with VLAN WAN interfaces as it seems.

                                            I've yet to see this here on any system. If anyone has a way to replicate this please let us know so we can dig into it.
