What type of data sets do you see lock ups on?
Errr, the cow "dataset" :)
What is the rest of your hardware specs?
Intel Core2 Duo, 3 Gb, single monitor.
The gfx card has 512 Mb, but that will hardly have any influence here.
Just tested with vsync turned on and now I get a lockup of a few
seconds, followed by
Threading model 'CullThreadPerCameraDrawThreadPerContext' selected.
Warning: detected OpenGL error 'invalid operation' after
RenderBin::draw(,)

RenderBin::draw(,)
[endlessly]
This is still with cow.osg.
I'll see what downgrading the nvidia drivers does for this
Well, going back to 169.12 does seem to make that problem go away (but
the non-vsynced framerate has gone down to about 1/10th of what it was
with the 173 series, doh!)

FYI, I haven't seen lock ups with toggling threading models, just
tried it again and no problems so we'll need to work hard to reproduce
elsewhere. My system is Quad core Intel, 4GB, Kubuntu 7.10, 64bit,
8800GTS 640Mb.

I seem to be getting some lock up when switching threading models in
osgviewer (with the cow). However.... I also see these in 2.6.0 now
that I
test it (haven't been using 2.6 yet).
What's more, switching of the threading model with 'm' does not always
seem to happen. Sometimes when I press 'm' the threading model doesn't
change, only when I press 'm' again.
This is with vsync off, b.t.w., in case timings issues might be at
play
here.
The lockup always seems to occur when switching to
CullThreadPerCameraDrawThreadPerContext. Here's a relevant stack trace

Hi All,
I am planning to make a 2.7.3 dev release tomorrow morning, there
have
been plenty of changes checked in since 2.7.2 so there is potential
for build breaks so I'd appreciate testing across platforms of
svn/trunk.
If you have a clean build or a build failure please post your results
into the list so I can keep tabs on where things are build/what is
left to fix up.
Thanks in advance,
Robert.
