This sets up OpenGL state - projection and view matrix, read/draw
buffers, color mask and viewport/scissor arar. Most of it is
overwritten by osg later, so may be it is not needed.

I don't know how the slave cameras are supposed to work, but there
should be one render pass in each Channel::frameDraw, using the
parameters given by Equalizer.
A Channel may draw more than once with different parameters, and it
might read back the result after each pass.

This looks like you are trying to commit or sync an eq::net::Object
which is not registered or mapped, e.g., the object's id is
EQ_ID_INVALID.
Distributed objects have a change manager helper class, which manages
the data distribution. The NULL change manager is the place holder for
unmapped objects.
Set a breakpoint in the line mentioned, and check what type of object
it is, and from where it is called.
HTH,
Stefan.
