Hi,
Thanks for reply and sorry for uncomplete
information.Now I am explainging all detail for above
mention error.

pid 5 (sh), uid 0: exited on signal 10 (core not
dumped, err = 30)
Jan 17 05:45:39 init: single user shell terminated,
restarting
-------------------------------------------------------
The above error detail is appeared when I try to going
into single user mode through sh shell.
but if I used ksh shell then the machine going to
single user mode and giving following errors,when I
execute system command.
-------------------------------------------------------
Enter pathname of shell or RETURN for sh: /bin/ksh

-------------------------------------------------------
The intresting thing is that some command are running
and some command are not like dmesg,ifconfig etc are
running and ls,ps route,netstat are not running.when i
try to execute the command then memory dump are
generated.
-------------------------------------------------------

dumped, err = 30)

-------------------------------------------------------
The last thing is that after execute "halt" command
then the following error are generated.
-------------------------------------------------------
 halt
