woops : forget to mention our JVM option at startup time : 


  | jvm_args: -Dprogram.name=pdm.bat -Xms1024m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:+DisableExplicitGC
  | 

Also : this is running on HP Server Quad Core / Windows 2003 SP2 / 4GB Memory. When the JVM crashes the GC output is :
