there is a chance that the c++ interactor is performing a render while 
your data is loading.  also could be that there really is a chance of 
another thread accessing the data at the same time.  what does your load

event thread is starved.  really can't diagnose your problem without 
some code.  can try ctrl-\ to get a thread-dump if you use jdk1.4, 
otherwise its hard to see where the hang occurs.
