Thanks Paul, 127.0.01 is in the /etc/hosts

127.0.0.1       localhost.localdomain   localhost.localdomain   localhost4      localhost4.localdomain4 localhost
::1     localhost.localdomain   localhost.localdomain   localhost6      localhost6.localdomain6 localhost

Thanks Uli

Unfortunately, the software I need to use do not support RHEL7 so we have to stick with RHEL6.  

I tried opening terminal, but still have some problems.  I  assume "single application > terminal" is the way to do this.

The crash happens ind XkbSendMap(). So I suspect some client in your
session asking nxagent for the xkb keyboard configuration. You can
look if you can disable that client. I suspect running a simple xterm
via x2go will not crash the session. Can you confirm?
