Hi, I have successfully established a multi-user capability, allowing multiple users to access and use the headless server’s resources. However, I am experiencing frequent system crashes but there is enough memory available.  
I refer to this [https://github.com/Kitware/trame/tree/master/examples/deploy/docker/SingleFile](https://github.com/Kitware/trame/tree/master/examples/deploy/docker/SingleFile) and install vtk based on egl.

Do you have a proxy (nginx?) that cut the WebSocket connection?

Is there anything special on your setup that you can tell us?

Are you sure the rendering/GPU access works as expected?

I don’t have any proxy. And also I tried both osemesa and egl version of vtk but it still crash frequently. Can you tell us how to investigate the cause?  
Thanks.
