Can you send me a traceback? Which version of the loader?

If you have not disabled PFFLT_CLEANNODE processing in the
loader, it is almost certainly deleting extraneous nodes from
the scene graph. If you are attaching user data to said nodes
and/or saving pointers to them that may be part of the problem.

It sounds like an MP problem wrt memory access but without
more hard information ... it's hard to diagnose.
