<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>
</p>
<p>Thanks for the answer!</p>
<p>Yves<br>

<div>Hi Yves !<br>
<br>
</div>
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>
<br>
</div>
Best Regards,<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 moz-do-not-send="true"
class="m_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
moz-do-not-send="true"
class="m_3538402776635204479moz-txt-link-freetext"
href="https://nixos.org/nixos/packages.html"
target="_blank">https://nixos.org/nixos/<wbr>packages.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>
