currently, I’m running the latest 5.12.0 in client/server setup. After connecting the client to the server. if I click help/about to see details, it abruptly closes the session and in the server, it says segmentation fault.
client in Windows 11, server in Ubuntu 23.10

Are you using the official binary release on both sides ?

5.12.0 is not out yet, are you using RC2 ?
There is an issue with osmesa currently, maybe it is this specific issue: [https://gitlab.kitware.com/paraview/paraview/-/issues/22350](https://gitlab.kitware.com/paraview/paraview/-/issues/22350)

Alternatively, you can always try 5.12.0-RC3. Be sure to use this on both client and server.
I have seen this before when the server side Python is bad or mismatched. Everything runs fine until you do a Help/About (or Programmable filter or somesuch). Help/About loads the server side Python, which then crashes.

Is there any log stored about the crash so that I can debug it

YOU create the log. You state you are remote server, I assume running pvserver in parallel. How do you launch the parallel job? If its qsub, there are arguments to write output and errors to files.
If I had do speculate on a possible cause of your problem, are you setting PYTHONPATH? This may be overriding the default in the Kitware build. Other than that, I have no idea…

@gpuligundla
Please check if this is the issue I linked above, related to glibc version.
Simple check to see if you are affected by this issue, just run:
`/lib/x86_64-linux-gnu/libc.so.6`
If it says anything above 2.35, you are most likely affected.
Best,

This is not as trivial as using the EGL release that woks out of the box.

What all flags i need to pass if I need a headless Osmesa setup in my ubuntu without any errors while building
In `https://gitlab.kitware.com/paraview/paraview-superbuild/` after cloning how to build, the steps are missing(I’m new to cmake)
