- Scenario
 I have the machine (12 GB ram), allocated 4GB heap for RTC.
when i start the extraction of workspace, i see that my 12 GB of free memory started getting used up, and at the end of source code extraction, i was left with almost 5GB only.
 When i checked the
ps -eaf | grep -i java | grep -i rtc i saw that RTC java is running

when i have seen the  ps -eaf | grep -i java | grep -i rtc | wc -l
24

i see 24 rtc java processes are running.

When i started the source drop again, i have seen that i was left with only 100 Mb of memory and this time i have seen 48 java rtc process running.
eventually when i start again, i see the machine will go to hang state and will never respond, only option i see is to reboot the system.

My question here is why are the java processes not getting killed here after successful completion of source extraction, and what is the solution to this problem to resolve this hang issue

I am using Red Hat Enterprise Linux Server release 6.7 (Santiago)  x86_64 (64 bit machine)

i am using the below script
lscm login -r https://isljazzrtc.in.ibm.com:9550/ccm/ -n localwork -u ${1} -P ${2}
rm -rf /source_drop/s810/$3
mkdir /source_drop/s810/$3
cd /source_drop/s810/$3
pres=`pwd`

while read line
do
        mkdir $line
        cd $line
        date
        lscm load ${3} $line -r localwork
if [ $? -eq 0 ]
        then
                echo "READY extraction is success"
                date
        else
                echo " READY extraction failed"
                exit 1
        fi
#mv src $line
        cd $pres
done < /usr/scripts/s810comlist // s810comlist is the component name list
