install problems

[K Sambaiah]

Hi,
   I have a problem installing RedHat linux 6.1. I wanted to install
via NFS mount so I made bootnet.img correctly. After loading some 
packages suddenly it gives errors like
  traceback (innermost last);
File "/usr/bin/anaconda". line 225, in ?
File "../../../RedHat/instimage/usr/lib/python1.t/site-packages/text.py"
line 1000, in run File
line 572, in __call__ if todo.do 
and terminating in the middle.
What are these errors? I would like to know where is the problem?
TIA,
