      Hmm, well if you can reliably recreate the issue then I would initially be looking at states in the firewall(s) to be sure traffic is arriving from the test clients.

      I have no reason to think upgrading will help here but obviously upgrading should work so the first thing I would do is at the command line run pkg -d update. If that returns without an error I would try upgrading from the console menu option 13. Both those will give you a lot more debug info.

        Sure, I can look at that. I assume I'm given options to continue or not before committing.

        I didn't look at the states so guess I need to do that next.

          Yes, for upgrading from the console you are asked if you want to continue before the upgrade happens.

          The pkg update runs immediately but does do anything beyond updating the list.

                Nice, I'll check that out later then. It's never a problem when it's a vm as they are so fast to reboot but enterprise hardware, go get a coffee.

                Update
                Strange, it updated just fine on two others that were 2.5.2 but this one I mention, nothing. I've not tried from the cli yet, trying to pick the right time.

                Update
                The only thing I notice is that one of the 2.6.0 is now showing memory usage of 40% on an almost no traffic network that usually shows 2-3% usage.

                I know there was a problem with the previous version where it would use up and not release memory and that was related to ipsec but I don't have it enabled on this config, or any for that matter.

                  40% of how much? With HAProxy running?

                    This one has only 4GB in it because it's very low traffic and on a 50Mbps connection. Maybe I never noticed it was at 40% but I think it would have gotten my attention.

                      You can check the process list in Diag > System Activity to see if any one thing is using it.

                      If not and it is not actually exhausted it's probably not an issue.

                        Nothing really obvious other than this;

                        2275 root 20 0 9988K 1368K select 1 0:00 0.00% /sbin/devd -q -f /etc/pfSense-devd.conf

                          Can we see the actual usage screen? 1.4MB is nothing, something must be using more than that.

                            Do you mean the dashboard or all of the processes?

                              The processes. So for example the output of top -aSPo res after a few cycles, like:

                                That's what I thought but wasn't sure :).
                                Nothing too unusual.
                                I never noticed that before, 42M active, 118M Inact, 1471M Wired.
                                Is the system holding some memory in some sort of buffer or something?

                                I've never seen that on Centos or other flavors I've worked with.

                                  Mmm, so just wired memory from the kernel (probably).
                                  It's not an issue as far as I know. If the actual free memory runs low the kernel will start releasing wired memory. It is different behaviour to 2.5.2 though.

                                    Sorry it took so long to get back to this but there is definitely something wrong with haproxy, at least on our device.

                                    For the past while, we've been testing everything possible inside our network thinking something between the web connections, the application and the database must be wrong.
                                    After an insane amount of hours troubleshooting, we could simply find nothing what so ever wrong with the application. The only clue was that clients were not communicating at the intervals they are set to.

                                    Eventually, we decided that maybe it's the Internet. Maybe because of the Ukraine war and lots of extra world wide hacking, maybe governments are filtering the net so much that it's caused some latency.

                                    Yes, we started thinking it must be the Internet! :).

                                    Then something dawned on me tonight after spending the entire day on this again. I remembered that I took haproxy out of the mix (as posted above) and things got way better there. Users are no longer getting gateway timeouts. I've been monitoring the logs since then.

                                    This evening, I decided to take this other set of servers off haproxy, put just one online and give traffic direct access. Guess what? The timing is now almost dead on, no longer random and no more missing connections.
                                    All data that is supposed to come in, is coming in, no missing data. It's haproxy causing the loss somehow.

                                    Here is a snip of us watching the logs and everything else a while ago. See the difference in timing? I'm only showing a snip but before haproxy was taken out, this client kept missing sending data, now it's dead on.

                                        Maybe the seg fault warnings are related to the haproxy problem.
                                        I don't know and I'm not sure what to think now. Feels like the firewall might fail at some point which would be bad.

                                          If it's HAProxy not passing the traffic somehow then you should be able to prove that easily using a packet capture on the WAN side. You would still see the connections coming in from the client at regular intervals.

                                          One thing to bare in mind is that HAproxy is an actual proxy so to changes the path of the connection compared to port forward. That might be relevant with the multiple WAN setup you have.

                                          Is there anything logged from that segfault? That doesn't seems familiar at all in 2.5.2.

                                            Well, what ever I do, it cannot be disruptive. Tihs problem plagued us to the point that members never came back, blaming our services.

                                            I don't have any multiple WANs on this, traffic coming into this firewall is simply port forwarded to devices on its LAN and we were using haproxy.

                                            The multiple WAN you mention are simply other firewalls that have their LAN side on the same 'cable' but simply co-exist with each other but in different networks.

                                            I didn't get a chance to check for proof but I could set up another test to an isolated server on the LAN. It would just show the irregular traffic as I showed. I don't have physical access to inject something between the WAN and a device to monitor. Everything else seems to work as it should, just haproxy is showing this behavior.

                                            As for segfaults, that was the first time I've seen those last night but it was also the first time I tried upgrading from the cli as you had suggested.
