Hi Hailong, The OSG itself places no restriction on the number of texture units, but some OpenGL drivers can do, particularly for the fixed function pipeline, perhaps you are hitting up against this. I know that NVIdia have recently reduced the number of texture units they support using the fixed function pipeline.
