Dear Murray,

   Thank you for your repid reply.

   My OS is 2.6.24.7-92.fc8 x86_64
   My java version is 1.6.0_03( 64-bit), J3D version is java3d-1_5_1-linux-amd64
   

   The last attached file is only demo code that I extract from my application. 
My application has 4 DisplayImplJ3D s in JTabbedPane. If I use only 1 
DisplayImplJ3D as the last demo code file, then loop is ok, although the lots 
of system memory is used; but when I use 2 DisplayImplJ3D s, the memory is 
eaten up rapidly and the loop is stop by the error message in console : 
java.lang.OutOfMemoryError: Java heap space ...

   I'm trying to extract the code from my application with 4 DisplayImplJ3D and 
demo data .

   Thanks again

Best,
Lizhi
