BI PUBLISHER unable to shutdown via scripts

I am unable to shutdown bi publisher services with this script wrote. I can shutdown all services via the management console just fine, but this script will not work.

We are running Oracle BI Publisher 11.1.1.7.0

echo -e "Stopping Components....opmnctl...."
............./instances/bin/opmnctl stopall > /dev/null 2>&1 &

sleep 90


echo -e "Stopping Managed Server: bi_server1..."
................../bifoundation_domain/bin/stopManagedWebLogic.sh bi_server1 http://ovm-bipub.<DOMAINNAME>.com:xxxx/ > /dev/null 2>&1 &

sleep 60

echo -e "Stopping Node Manager....You need to kill service manually. (testing now with a kill -9 command)"

#There is no 'stopNodeManager', must kill associated proccesses
kill -9 `ps -ef | grep -i nodemanager.javahome | grep -v grep | awk {'print $2'} | head -1`

sleep 5

echo -e "Stopping Weblogic Server...."
