I tried it with '$useVGL = 1' as well and was still unable to reproduce the issue.  (Note that, from the point of view of the application, setting '$useVGL = 1' in turbovncserver.conf or starting the TurboVNC session with '-vgl' is the same as launching the application with 'vglrun +wm'.)

I also tried with both CentOS 7.9 and CentOS Stream 8.  My CentOS 7.9 machine has a Quadro K5000 with driver v470.xx.  My CentOS 8 machine has a Quadro P620 with driver v510.xx.

Is there any way that you could try running the Tecplot batch job on the 3D X server without VirtualGL?  If it fails in the same way, then it isn't our bug.

Hi DRC,

sorry, I forgot to comment out that module command, that would only add the Tecplot installation PATH to the bash PATH variable, But as I see from your output the tec360 command in Tec360_FlowViz_batch.sh started fine, so it is already in your PATH, so all good.

Did that tec360 run end without errors?
Is your setup also using $useVGL = 1; in /etc/turbovncserver.conf ?
Just guessing possible differences.

Thanks for testing,
Richard

    Please clarify how this is supposed to work.  'module load' is not
    a valid Bash command.

        Hi DRC, hi all,

        First, thanks DRC for this great software!

        We are having some issue with Tecplot / tec360 and VirtualGL:
        Some system specs:
        Rocky Linux 8.5
        VirtualGL-3.0-20211119.x86_64
        turbovnc-2.2.90-20211222.x86_64
        NVIDIA Corporation GM204GL [Tesla M60]
        Tecplot 360 EX 2021 R2, Version 2021.2.1.9698 (Feb  3 2022)

        VirtualGL is configured with both GLX + EGL back ends.
        $useVGL = 1;   in /etc/turbovncserver.conf

        While trying to run tec360 on batch mode we get the attached
        error output.
        Here the last 10 lines:

        Tecplot received shutdown signal.
        Signal #11
        Please send the output above to Tecplot support:
        [email protected]
        /net/c1m1/data_1/opt/Tecplot360/360ex_2021r2/bin/tec360:
        line 349: 276303 Aborted                 (core dumped)
        "$0-bin" "$@"



        Any ideas what is going wrong?
        When running with tec360 option "--osmesa" all runs fine,
        but it takes 17 min to run.

          --osmesa
            Bypass the OpenGL library and use the LLVM OSMesa
        library for off-screen
            image rendering. This option does not require an X
        server connection.


        Best regards,
        Richard
