Hi Roland, thank you for the reply. 

I have tested with bash, sh and csh. It seems the child process forked 
simply die irrespective of the shell. 

There  is no change in the dot files for root:
[root at tds sagara]# diff /root/.cshrc /usr/src/etc/root/dot.cshrc
[root at tds sagara]# diff /root/.login /usr/src/etc/root/dot.login
[root at tds sagara]# diff /root/.profile /usr/src/etc/root/dot.profile 

Here is the log message for "su -l":
Jul  2 12:38:17 tds kernel: pid 943 (su), uid 0: exited on signal 11 

Btw, what is "restart commands file for root"?
