I got it. The problem was that I used a set() function for a field in
the RenderChannel constructor (That worked without problems in 1.8

glad to hear you found the problem!
For this kind of initialization there is onCreateAspect() (must call the
base class' onCreateAspect), which is called after the container is
registered with the FieldContainerFactory (and thus has a valid id).
That caused the _pContainerChanges entry to be created. But the
initialization of it was corrupt as the RenderChannel instance was not
yet aware of its containerID. As the cleanup of pContainerChanges is
triggered by containerID it was never successful.
So this is actually no bug in OpenSG but maybe it would be good to have
a warning message or some kind of special handling in
registerChangedContainer() if the containerID is set to 0.
I'm adding the attached, which hopefully catches these cases in debug
builds.
Cheers,
Carsten
