Hi There,
  I am using McIDAS,  a large java program for displaying  weather/climate data.
  For 3d/2d rendering it uses the java3d API -  ( the two jars j3dcore and j3dutils.jar dated 2008)
 The program can run in two modes interactive and script mode.
  In script mode instructions  are taken from  python script and the main window is NOT displayed.
 ( nb this is NOT in headless mode)
 
 On our server the program runs fine in interactive mode  - but in script mode  when doing a batch job ; the program opens loads of threads (110-150)  and uses lots of heap memory ( 4GB)  and then eventually grinds to  halt .
( see threads at end of post)
On my local machine the batch jobs runs fine,


The sever specification is
server:
quad core Xeon running CentOS 6.4

Graphics card:
GeForce GT 610 (rev a1) - driver nvidia version 319.17

java- runtime:
 ( comes bundled with the McIDAS sofwtare)
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)



Any help or insight would be very greatly appreciated
..Henry
