Hi John,
you could try and disable OpenGL acceleration for WX Gui. That's usually
not a good thing, and it doesn't always help if your system randomly
hangs in WX things, but if it solves this:
find (or create) your ~/.gnuradio/config.conf and add
[wxgui]
style = nongl
Best regards,
Marcus

Hi,
Have GNURadio 3.7.9.2 installed on Ubuntu 15.10. I have been
running simple_ra but don't believe that is germane to the problem at
hand.
I am running simple_ra_receiver under debug (have seen
segmentation errors in libc in the past and trying to narrow down)
but, again, don't think this is a factor in the symptom.
Traceback (most recent call last):
File
"/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/plotter_base.py",

err = 1285,
description = 'out of memory',
baseOperation = glCallList,
cArguments = (2L,)
)
The graphics screen is frozen (grey) but the rest of the threads
run OK.
In terms of system memory, shows 1.9GiB of 15.6 so I don't believe
the system is running out of physical memory.
Cannot find anything relating to this issue vis-a-vis GNURadio.
Any ideas of what is going wrong or a workaround I could implement
to avoid?
Kind Regards,
John
