No idea.  I'll have to try to reproduce it on my local machine.

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:

/net/c1m1/data_1/opt/Tecplot360/360ex_2021r2/bin/../bin/libtpsdkbase.so(TecEngStartup+0x24) [0x7f93fdad0394] /net/c1m1/data_1/opt/Tecplot360/360ex_2021r2/bin/../bin/libtpsdkintegrationmanager.so(_ZN7tecplot3sdk11integration15ManagerAbstract5startEv+0x19) [0x7f93fe92b1b9]

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
