Redhat 7.2 crashes when I close a visad application

Has anyone out there who develops on linux run into the problem where linux 
logs you out when you try to close an application running visad?  I also 
sometimes get logged out when I try adjusting the z-scale or the colors being 
mapped to my visad display.  I noticed an old thread which suggested updating 
to the latest version of glibc, I've tried this and it doesn't solve the 
problem.
 
Thanks,
