Hello Catherine,
if you know the token of the associated session, you can use:
utload -r -t $TOKEN
I use the following script to get rid of hanging sessions.
It's also useful when a server in a failover group had to be rebooted and all
idle login sessions are on the remaining servers. After rebooting the server
just run the script on the other server in the FOG to make sure idle login
sessions move to the freshly rebooted machine.

#!/bin/bash
# kill all sessins, that do not belong to a user
# kill all Xnewt servers, that do not belong to a session
# set PATH
PATH=$PATH:/opt/SUNWut/sbin:/opt/SUNWut/bin:/opt/SUNWut/lib
# get sessions with NO "Unix ID"
utsession -p -x \
| grep uid=NULL \
| cut -d ";" -f 1 \
| cut -d "=" -f 2 \
| while read TOKEN
do
# reboot DTU
utload -r -t $TOKEN
echo "rebooting DTU $TOKEN"
# kill session
echo "killing session $TOKEN"
utsession -k -t $TOKEN
done
# get running Xnewt prcesses
ps ax -o pid,command \
| grep -v "grep" \
| grep -e "Xnewt :[0 9]*" \
| sed 's/ //' \
| cut -d " " -f 1,3 \
| sed 's/ //' \
| while read PROCESS
do
DISP=$(echo $PROCESS | cut -d ":" -f 1)
PROC=$(echo $PROCESS | cut -d ":" -f 2)
if [ $(utsession -p -x | cut -d ";" -f 5 | cut -d "=" -f 2 | grep $DISP) ]
then
echo "killing hanging Xnewt with PID: $PROC"
echo "kill -9 $PROC"
fi
done
