        I don't see that using your sysctl list but I do see:

        Setting up extended sysctls...sysctl: net.inet.tcp.cc.algorithm=htcp: No such process
        sysctl: net.inet.tcp.cc.algorithm=htcp: No such process
        done.
        

        what does it mean?

          Yeah, can we see where in the logs you're seeing this? Can we see the complete boot log?

          I'm seeing that error because htcp is not an available algorithm in 2.5.2:

          [2.5.2-RELEASE][admin@252dev.stevew.lan]/root: sysctl net.inet.tcp.cc.available
          net.inet.tcp.cc.available: newreno
          

          So that tunable you have is invalid there.

          Where did that list of sysctls come from?

          Steve

                There's no error shown in that log.

                You are loading additional modules if you see htcp available. What else are you loading?

                Do you have a /boot/loader.conf.local? What's in it?

                    Yup because in order to see that as an option you have to load the module:

                    [2.5.2-RELEASE][admin@252dev.stevew.lan]/root: kldload cc_htcp
                    [2.5.2-RELEASE][admin@252dev.stevew.lan]/root: sysctl net.inet.tcp.cc.available
                    net.inet.tcp.cc.available: newreno, htcp
                    

                    It's not loaded by default because it's pointless for the vast majority of users.

                    So OP is loading it via some custom loader variable which begs; what else is being loaded? 😉

                    Whatever it is it's probably generating that error. Which we've yet to see in context.

                        Ok.

                        Why are you loading those things?

                        One of those is causing your error.

                          Good day!
                          What specific parameter from the boot/loader.conf.local confuses you?

                            This information on tuning FreeBSD hosts connected at speeds of 1Gbps or higher.
                            FreeBSD supports TCP autotuning and advanced congestion control algorithms in all currently-supported releases. You can check which are available in the running kernel using:

                            sysctl net.inet.tcp.cc.available
                            To make additional algorithms available in the kernel, the appropriate module must be loaded. The congestion control modules are in /boot/kernel and begin with cc_ - they can be listed with the following command:

                            ls /boot/kernel/cc_* | grep -v symbols
                            To load a particular congestion control algorithm (for example htcp) you can use:

                            kldload cc_htcp
                            and you will then be able to set the congestion control algorithm using this:

                            sysctl net.inet.tcp.cc.algorithm=htcp

                            Enabling congestion control algorithms at boot time

                            Depending how your kernel is built, you may not have the algorithm you want available by default at boot time, and will need to load the driver during the boot process. To to this add the following to /boot/loader.conf:

                            cc_htcp_load="YES"
                            The htcp algorithm will then be loaded at boot time, and will be enabled when sysctl.conf is processed at boot time and the net.inet.tcp.cc.algorithm=htcp variable is set.

                              Right but a firewall/router is not a host. Almost all traffic passes through it and those TCP tunables apply to traffic terminated on the system.

                              Why have you added them? Were you seeing a problem? Did it help?

                              One of those is causing the error you are seeing. So if you want to not see it you need to stop applying that tunable.

                                      You still have not shown us the log containing this error for context so we can only guess what is calling it. You must have something custom on that box.
                                      To confirm you have removed the custom sysctls from Sys > Adv > System tunables?
                                      sysctl.conf will just get rebuilt at boot.

                                            Ok, so it occurs multiple times and not just at boot? Some minutes apart?

                                            Does it log that continually?

                                            That's not a sysctl that is applied at boot then. You have something else on that system actively setting something that's no longer valid. Do you have something else running there? Some other custom script or manually added package?
