Hi Chang, This is probably due to a static initialization of the various proxy objects.
OSG-3.2 has a few bug fixes related to initialization and might help, but in general I have to say the plugins aren't written to handle multi-threaded initialization. Once they are initialized it should be safe to run them multi-threaded. Robert.
