      Ok, the server crashed again. The more detailed log didn't show much, but here it is nonetheless:

      openvpn.log:

      Nov 23 04:33:57 kernel ovpns1: link state changed to DOWN

      In openvpn.log there several connection attempts in a row from the same IP address, then the server crashed. Now all that remains is to try the solution suggested by ogghi above (pkg upgrade). I hope this works.

        I think it will work.
        It hasn't crashed here anymore!

        I am wondering if there is any official statement from Netgate or so?

          Yes, I also updated the OpenVPN package via pkg upgrade and now all that remains is to monitor the stability of the server. You are right, it looks like netgate has updated the openvpn package in its repository since the release of 2.7.1, but has not said anything about it anywhere. In any case, pkg upgrade is the only thing we can do about this problem for now.

            It seems stable here in regards to disconnects, but people using remote desktop sometimes get some timeouts as it seems. Keeping an eye on logs today.

            Happy Monday ppl!

              OpenVPN released OpenVPN 2.6.8 which addresses a segfault that some users see with 2.6.7:

              https://github.com/OpenVPN/openvpn/issues/449

              https://openvpn.net/community-downloads/

              We're still discussing what the best course of action is to address it since it doesn't seem to be widespread.

                we are also affected by random openvpn crashes, this setup running before over 8 years without any issue.

                There are many different openvpn clients and version on this server, maybe this combination trigger the issue more...

                  We'll be bringing in OpenVPN 2.6.8 to the next patch release (Plus 23.09.1, CE 2.7.2) which should be out here in the next week or so if all goes according to plan.

                      Nothing public yet, but it's primarily security/stability things. The ZFS corruption bug, OpenVPN needed a version bump, so did strongSwan, various fixes in PHP code. Not a long list, but significant enough to warrant a patch release.

                          FYI- If you are on Plus 23.09 or CE 2.7.1 we picked back the update to the current repositories so you can also get OpenVPN 2.6.8_1 right now from the console or SSH shell prompt:

                          # pkg update
# pkg upgrade -y openvpn

                          And then either restart each instance manually or reboot.

                              We had one virtual instance of pfsense that had the OpenVPN remote access server crash every 2-3 days. After pkg update the server has been running without problems for 5+ days.

                                We can confirm this, no issue since 2.6.8_1, thank you @jimp

                                Simply reinstall of the package openvpn-client-export does also the OpenVPN upgrade.

                                  Thank you a lot @jimp , it works for me since more than 20 days now. We have 3 OpenVPN servers.

                                    It's seems to be solved for now (running almost month without crashes). To solve problem do from console from root:

                                    pkg update
                                    pkg upgrade -y openvpn

                                    Or just upgrade to latest release! For me, openVPN run as rock solid after i do upgraded the package and then update system to the latest stable release 2.7.2! Thanks All Guys!

                                      I just ran into this crash, same errors as OP.
                                      This is the first time i've ever seen the openvpn server crash. Usually my prod system is a i3-4130 (for years now), but i've been testing on an n100 system for about a week now and this crash just happened. Same pfsense version and config from the i3 system.
                                      I'm running pfsense 2.7.1 w/openvpn 2.6.8_1 so the new version doesn't fix it

                                      # pkg info

                                        I'm running pfsense 2.7.1

                                        Be aware that those who are using 2.7.1 are not the persons who visit this forum.
                                        As they would see right away that 2.7.2 was avaible. Did you test 2.7.2 ?

                                        I'd love to add more details, but 2.7.1 is more then two years old and I can't recall any related info anymore.

                                        No "help me" PM's please. Use the forum, the community will thank you.
                                        Edit : and where are the logs ??
