3 steps to kill the process:
1. "who -u" to find out who you want to kill:
$ who -u
dba pts/0 Jun 5 09:33 1:10 6749 192.168.0.122

2. "ps -ef |grep sh" to find out which sh process associated with the pts/0:
$ ps -ef |grep sh
dba 6749 6747 0 09:33:33 pts/0 0:00 -sh
3. you may now kill the sh process 6749:
$ kill -9 6749

You most likely have a corrupted entry in your /etc/utmp file.

Convert the file to ascii
#/usr/sbin/acct/fwtmp < /etc/utmp >/tmp/file
edit the file and remove the corresponding entry for that user and his corresponding tty.

Then can convert it back to binary form:
# /usr/sbin/acct/fwtmp -ic < /tmp/file > /etc/utmp

All that means is that by the time you issued the kill command the process had ended.

BTW - kill -9 should ONLY be used IF a normal kill....
kill PID
or
kill -15 PID
have no effect.
kill -9 can leave unreturned memory, msg or semaphore entries that will not be reaped w/o intervention.
MORAL: kill cleanly or silently or don't kill at all.

Hi.
You can use "ps -t pts/0" to see what the user's running processes,and kill the process id by kill -9.
