[Paraview] Is there a maximum limit of memory use in a single process?

[weaponfire2005]

Hi all:
  First thanks for David's help.
  When I run paraview, I find that paraview will report error if one process consume more than about 2.5GB memory. It says that "unable to allocate xxxxx 4 bytes float" or something else. There are 8GB memory on my computer. Is it caused by my OS? For my OS is 32-bit RHEL, are there some resolutions for this? Or I must change to 64-bit OS?
  Thanks for your help.
  Pan Wang
