Memory problem

Sorry, of course your are wright. I'm running Python2.5 on Linux, my 
program imports numpy, matplotlib, sys and a python module of my own.
This module uses numpy and scipy.weave for imbedded C-code but no 
extension modules. I though the code to be to large to show, I hoped you 
could give me hint on what I could try.

Thank you in advance
