      Hi there,

      after an update of Kopano, I noticed the gateway-process die:

          @Stephan said in Gateway Process dies:

          Any ideas?

          i fixed this by : backup /etc/kopano

          remove kopano.
          Now go searching for leftovers of kopano.
          apt install mlocate && updatedb
          locate kopano

          Clean these leftovers up.

          install kopano

          and its fixed.

          Worked for me 3 times.

            Thx a lot!

            Do you know anything about the root cause or a less invasive approach?

            I’m a bit nervous, uninstalling a production server ,-)

              The root of the problem, yes, if you have used the daily packages, ( the community packages), some of these have some left overs, multiple .py files, after removing kopano, the left overs needs to be removed.
              Then you can install them again.

              Just dont purge, and caputer all package which are removed.

                @fbartels: will there an official fix for the gatewaycrash? We had this issue today for the second time.

                  @irrlicht I have not yet investigated this, but I doubt the gateway is crashing because of some leftover .py files.

                  If you have a subscription I recommend to get in contact with our support so they can help you investigate.

                    quick&dirty-solution for Debian Stretch (systemd), hope it works

                    /lib/systemd/system/kopano-gateway.service

                    add:
                    Restart=always

                    [Unit]

[Service]
Type=simple
ExecStart=/usr/sbin/kopano-gateway -F
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target

                    After edit:

                    systemctl daemon-reload

                    @fbartels: perhaps this would be a good default setting?

                      @irrlicht probably cannot hurt. If you want you can open a pr with your desired changes.

                      You can find the file at https://github.com/Kopano-dev/kopano-core/blob/master/installer/linux/kopano-dagent.service
                      The easiest is to open a pr on Github and we just pull this into our internal git. Alternatively you could follow the instructions at https://stash.kopano.io/projects/KC/repos/kopanocore/browse/CONTRIBUTING.md.

                        If you go that way…

                        systemctl edit kopano-gateway or systemctl edit --full kopano-gateway
                        And use the override files.

                        Dont touch the files in /lib/systemd/system/
                        it’s not needed.
