I have users of my simple\_ra application complaining of this:

Traceback (most recent call last):  
File  
“/usr/local/lib64/python2.7/site-packages/gnuradio/wxgui/plotter/plotter\_base.py”,

OpenGL.error.GLError: GLError(  
err = 1285,  
baseOperation = glCallList,  
cArguments = (1L,)  
)

After running for an hour or two.

This is on F22, but on F20, there’s no such issue. So, it appears that  
there’s a memory leak somewhere, but not sure where.

What hardware are they running this on ? (which GL driver)

Cheers,

Here’s info from one of the users:

Thanks for reporting the error on the mailing list.  
To answer Sylvain, here’s the chipset and Mesa driver I’m using. I  
suspect Dave also uses an Intel chipset.

$ glxinfo | grep -i opengl  
OpenGL vendor string: Intel Open Source Technology Center  
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile  
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.6.1  
(git-6ff3ae8)  
OpenGL core profile shading language version string: 3.30  
OpenGL core profile context flags: (none)  
OpenGL core profile profile mask: core profile  
OpenGL core profile extensions:  
OpenGL version string: 3.0 Mesa 10.6.1 (git-6ff3ae8)  
OpenGL shading language version string: 1.30  
OpenGL context flags: (none)  
OpenGL extensions:  
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 10.6.1

$ dnf list installed | grep -i mesa-dri-drivers  
mesa-dri-drivers.x86\_64 10.6.1-1.20150629.fc22 @System

I’m not a subscriber on the mailing list and I’m unknown there, maybe  
you could forward them this.  
If some debug info is required such as an strace, I’ll subscribe to  
their list and deal with them directly.

Regards,  
Damien
