I have done a lot more investigation in the context clean up issues
and have checked in a provisional fix for the issues. Could you
please do an svn update and then test against your own applications to
see if things are fixed.
The code I've just checked in still has lots of debug info
Hi J.P.
Thanks fort he test app + data, I'll look into this today. My guess
is that the issue will be close related to the crash that Nico has
reported.

I've tried out your example and found that with paged databases and
your supplied model everything works fine for the first viewer then on
the subsequent viewer I get:

Hi Robert,
This sounds the issue that I've been seeing with regards to context ID reuse

Hi Robert, Jason,
I would see similar crashes / missing textures, but only when previous
context ID's were reused, and only when using paged databases.
I'd sure like to see this fixed... I posted an example reproducing the
issue on osg-users a while back but Robert was busy on the GLES port.
Hi J.P,
I've modified the osgcamera example to have code path for testing a
series viewers, with sharing models and reloading them for each
viewer. I've written about it on the thread VBO's - lifetime..
I'm able to get GL errors when using VBO's, and with your test model
with a straight
Hi J.P.
I've just changed USE_NEW_TEXTURE_POOL to 0 and then tested:
osgcamera -r 3 earth_sphere_dt1.ive
And it doesn't produce any errors and model always comes up with
textures. So it does look like the new osgcamera test is sufficient
for testing this particular bug.
Robert.
Hi J.P,
The typical problem is that the scene graph has been set up to unref
texture images after apply so when it comes to reloading the texture
images there aren't the to download.

I'm still knee deep in merging submissions so can't yet go off
reviewing user code. In principle it is possible to mange open and
closing viewers. I can point you in the right direction but have to
let you get on with it otherwise.

Hi Robert,
it seems to be something broken on context destruction with the new

Can anyone confirm the missing textures? Any hints as to what else needs
to be done to make sure everything is cleared/flushed correctly?

I haven't had a chance to check your code yet, give me a few minutes and
I'll check if there's anything amiss that I can see.

Hi Frederic,
Since we don't have direct access to the textures, we can't make the call to
setUnRefImageDataAfterApply(). Would there be another way?
You can run a visitor to get to the textures and turn this setting off.
You can either make your own, or use

Hi Frederic,
Some more fun in perspective! At least, I'll try the texture pool solution in
the latest SVN build to see if it helps.
I think that's what's most susceptible to work. Even stable releases can
have bugs. So I really suspect that you're hitting a bug that's fixed in
SVN. As I
