    <p>Hi Mathieu,</p>
    <p>for info, here is the backtrace for the PV5.2 bug with seg fault
      when disconnecting (sorry it was stuck in my draft e-mails since a
      while :-). <br>
    </p>
    <p>I did not find the time to rebuild with the last version. I will
      try to do so soon... I think I have to rebuild it from source as
      the basic goal is to package it on nix system (which uses internal
      nix package dependencies). I currently use 5.3 RC2 for my
      developments and it works completely fine on any system (not
      including nix :-).<br>
    </p>
    <p>Bye,</p>

              <p>Hi Mathieu :-)</p>
              <p>yes it's for the case of multi-server (actually single
                client) option. I will get the source from the git
                repository master a give it another try.</p>
              <p>OK for the debug, I can compile it again in debug but
                it takes a long time on my little test laptop so I was
                wondering maybe some other tricky test on the release
                version ;-) I will let the debug build run this week-end
                and send a quick report.</p>
              <p>By the way, do you plan to support nix packages build
                in the future for Paraview ? The problem I will
                encounter now is that Paraview depends on video card
                driver OpenGL libs so that to get good performances, I
                will break the nix packages philosophy of being
                independent from the operating system specific kernel...<br>

                            Do you happen to use the
                            multi-clients/multi-server option ? we
                            recently corrected a bug that sound like
                            yours, will be fixed in ParaView 5.3.<br>
                          </div>
                          In any case, you may want to try with the last
                          version of paraview master.<br>
                          <br>
                        </div>
                        In order to debug, the first step would be to
                        build ParaView in Debug, and then run it with a
                        debuger, in order to get a backtrace of the
                        segfault.<br>

                            <p>Dear Paraview team,</p>
                            <p>we are currently studying the opportunity
                              of migrating our computing grid
                              environment from "module" system to "nix"
                              packaging system (<a class="m_-5571846420994025973m_8580887374267790081m_3538402776635204479moz-txt-link-freetext" href="https://nixos.org/" target="_blank">https://nixos.org/</a>).
                              In that purpose, I'm trying to compile and
                              pack Paraview 5.2.0 with its dependencies
                              with nix packages (<a class="m_-5571846420994025973m_8580887374267790081m_3538402776635204479moz-txt-link-freetext" href="https://nixos.org/nixos/packages.html" target="_blank">https://nixos.org/nixos/packa<wbr>ges.html</a>).
                              <br>
                            </p>
                            <p>To do so, I first installed nixos on a
                              local laptop and give it a try. The main
                              issue I encountered was to update my nixos
                              kernel with native videocard drivers but
                              OK, that's done. Then using the attached
                              nix package script (a slight evolution on
                              paraview 4.0.1 existing one), I could have
                              packetized 5.2.0 succesfully and it runs
                              very well.</p>
                            <p>However, I still get an error when I'm
                              trying to use MPI functionality. The MPI
                              itself with parallelism works, as I can
                              run a auto-MPI session without problem.
                              The issue occurs when <b>servermanager.Disconnect()
                                function is called => Seg fault</b>
                              with no more info... The bad thing is that
                              the Disconnect function is called every
                              time I would like to connect to a server
                              (to disconnect the built-in one). This is
                              also the case when passing the pvserver in
                              command-line argument.</p>
                            <p>Do you have an idea of the cause of this
                              seg fault ? Maybe could you help me find
                              any useful test to debug this ?</p>
                            <p>Thanks in advance for your support,</p>
                            <p>Best regards,</p>
