Deadlock after attemp
Reply with quote

Hi,

After starting our applications which use OpenSceneGraph 3.4.0. It appears that the program has deadlocked after calling osgViewer::CompositeViewer::frame().


Does anyone have any ideas what went wrong? Attached is a stack trace of all the threads.

...

Thank you!

Cheers,
Tony

Hi Tony,

I don't recall deadlock issues. Do the stock OSG applications like
osgviewer exhibit the same behaviour?

What platform/build options are you working with?

Robert.

Hi Robert,
We are running on Centos 6 with a 3.5.0 kernel. The OpenSceneGraph release is 3.4.0 with osgEarth with some changes in it for us. Our version GLSL is 4.40 and we are running the NVIDIA driver, which appears to be 340.96 on a NVIDIA GTX 660. The OpenSceneGraph version appears to have some patches in it based on what was in the RPM Spec file the we retrieved from the web.

The only error messages we have in our log file are:
Code:

Warning: detected OpenGL error 'stack underflow' at end of SceneView::draw()
[osgEarth]* [TileModelCompiler] Z-value not set for mask constraint vertex
[osgEarth]* [TileModelCompiler] Z-value not set for mask constraint vertex
[osgEarth]* [TileModelCompiler] Z-value not set for mask constraint vertex
[osgEarth]* [TileModelCompiler] Z-value not set for mask constraint vertex


Not sure what that means but my understanding is that this is the first time
our application has died like this.

I haven't tried running osgViewer but I expect it will work as it has in the past on the same system with the same libraries.

...

Thank you!

Cheers,
[/code]
